Description

[Technical field]

[0001] The present invention relates to a switch device, and more particularly to a push-type switch device. [Background technology]

[0002] A known switch device includes a pushable member that moves in a predetermined direction from a reference position toward a pushed-in position when pressed from the outside and returns from the pushed-in position to the reference position when released from the pressure, a plurality of fixed contact portions, and a movable contact portion that switches the conductive state between the plurality of fixed contact portions, and the movable contact portion moves toward and away from the fixed contact portions in conjunction with the movement of the pushable member (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3169859 Summary of the Invention [Problem to be solved by the invention]

[0004] In a switch device such as that disclosed in the above-mentioned Patent Document 1, since the movable contact portion is attached to the pressed member, the amount of movement of the movable contact portion is necessarily equal to the amount of movement of the pressed member. Therefore, if the stroke of the pressed member is increased in an attempt to ensure robustness against positional variations in peripheral parts that operate the switch device, the amount of movement of the movable contact portion will inevitably increase. If the amount of movement of the movable contact portion increases, the sliding distance over which the movable contact portion slides on the fixed contact portion increases, which causes a problem that the amount of wear of the fixed contact portion increases, and thus the contact reliability between the movable contact portion and the fixed contact portion decreases.

[0005] The present invention has been made to solve the above-mentioned problems in the conventional technology, and has an object to provide a switch device that can suppress a decrease in contact reliability between a movable contact portion and a fixed contact portion. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the switch device described in the present application comprises a pushable member that moves in a predetermined moving direction from a reference position toward a pushed-in position when pressed from the outside and returns to the reference position when released from the pressure, a biasing member that biases the pushable member toward the reference position, a plurality of fixed contact portions, and at least one movable contact portion that is arranged to be swingable in a direction intersecting the moving direction of the pushable member and switches the conductive state between the plurality of fixed contact portions, wherein the pushable member is formed in a direction oblique to the moving direction and has a sliding portion that can slide on the movable contact portion, and when the pushable member moves from the reference position toward the pushed-in position, the movable contact portion is pressed by the sliding portion due to the sliding of the pushable member on the sliding portion, causing the movable contact portion to swing and move toward or away from at least one of the plurality of fixed contact portions.

[0007] In the switch device, the sliding portion may include a plurality of inclined surfaces formed in stages in a direction obliquely intersecting with the moving direction of the pushed-in member.

[0008] In addition, in the switch device, the direction in which the inclined surface is formed when the movable contact portion is in contact with one of the multiple fixed contact portions may form a smaller angle with respect to the direction of movement of the pushed member, compared to the direction in which the inclined surface is formed when the movable contact portion is not in contact with any of the multiple fixed contact portions.

[0009] In addition, in the switch device, the movable contact portion may have an arm portion electrically connected to one of the multiple fixed contact portions, and the arm portion may be pressed against the sliding portion by the sliding of the push-in member on the sliding portion, causing the movable contact portion to oscillate and move toward or away from another of the multiple fixed contact portions.

[0010] In the switch device, the movable contact portion may have a plurality of contact portions that come into contact with and separate from at least one of the plurality of fixed contact portions.

[0011] The switch device may include a plurality of the movable contact portions.

[0012] In the switch device, the pushed-in member may have the sliding portion for each of the plurality of movable contact portions.

[0013] The switch device may further include a pair of movable contact portions, and the pushed-in member may have a pair of the sliding portions corresponding to the pair of movable contact portions.

[0014] In addition, in the switch device, the multiple fixed contact portions may have a first fixed contact portion and a second fixed contact portion, and the movable contact portion may be electrically connected to the first fixed contact portion, contact the second fixed contact portion when the pushed member moves toward the pushed position, and move away from the second fixed contact portion when the pushed member moves toward the reference position.

[0015] In addition, in the switch device, the multiple fixed contact portions may have a first fixed contact portion and a second fixed contact portion, and the movable contact portion may be electrically connected to the first fixed contact portion, and may move away from the second fixed contact portion when the pushed member moves toward the pushed position, and may contact the second fixed contact portion when the pushed member moves toward the reference position.

[0016] In addition, in the switch device, the multiple fixed contact portions may include a first fixed contact portion, a second fixed contact portion and a third fixed contact portion, and the movable contact portion may be electrically connected to the first fixed contact portion, and when the pushed member moves toward the pushed position, it moves away from the second fixed contact portion and contacts the third fixed contact portion, and when the pushed member moves toward the reference position, it moves away from the third fixed contact portion and contacts the second fixed contact portion. Effect of the Invention

[0017] According to the present invention, it is possible to suppress a decrease in the contact reliability between the movable contact portion and the fixed contact portion. [Brief description of the drawings]

[0020] <Application Examples> The switch described in the present application is an in-vehicle microswitch used for purposes such as detecting the position of a seat, detecting the opening and closing of a sunroof, and detecting the opening and closing of a door.

[0021] (Embodiment 1) -Switch device- Fig. 1 is a perspective view showing an example of a switch device 1A in embodiment 1. Fig. 2 is a see-through perspective view showing an example of an internal structure of the switch device 1A in Fig. 1. Fig. 3 is a side view of the internal structure of the switch device 1A in Fig. 2 as viewed from the left. Fig. 4 is a plan view of the internal structure of the switch device 1A in Fig. 2 as viewed from above.

[0022] In the figure, the symbol X indicates the front-rear direction (depth direction) of the switch device 1 (A, B, C, D), with the -X direction (negative X direction) being the front direction and the +X direction (positive X direction) being the rear direction. The symbol Y indicates the left-right direction Y of the switch device 1 (A, B, C, D), with the -Y direction (negative Y direction) being the left direction and the +Y direction (positive Y direction) being the right direction. The symbol Z indicates the up-down direction of the switch device 1 (A, B, C, D), with the -Z direction (negative Z direction) being the down direction and the +Z direction (positive Z direction) being the up direction. These descriptions are similar to those in the following embodiments. Note that the descriptions of these directions used in the embodiments of the present application are for the convenience of explanation and do not limit the arrangement direction of the switch device 1 described in the present application.

[0023] The switch device 1A in the first embodiment includes a housing 2, a pushed member 3, a biasing member 4, fixed contact portions 5 (5a, 5b), and a movable contact portion 6 (see Figs. 1 to 4). The switch device 1A in the first embodiment is structured such that the pushed member 3 moves back and forth in a moving direction D (+D / -D) along the up-down direction (Z direction), causing the movable contact portion 6 to switch the conductive state between the fixed contact portions 5 (5a, 5b).

[0024] <Housing> The housing 2 has a housing main body 20, a cover portion 21, and a cover fixing portion 22 (see FIG. 1). The housing 2 accommodates a pushed member 3, a biasing member 4, a plurality of fixed contact portions 5 (5a, 5b), and a movable contact portion 6. The housing 2 in the first embodiment is structured such that the cover portion 21 is attached to the top of the housing main body 20, and the cover fixing portion 22 is placed over the cover portion 21.

[0025] The housing body 20 is formed in a substantially rectangular parallelepiped shape (see FIG. 1). The housing body 20 is formed by, for example, injection molding using a synthetic resin material.

[0026] In the first embodiment, the housing body 20 has, at the upper part of the outer surface on both sides, locked portions 200 to which the cover fixing portions 22 are locked. In the inner surface of the front side of the housing body 20 in the first embodiment, a guide groove 201 for guiding the pushed-in member 3 in the moving direction D is provided along the up-down direction (Z direction) (see Figs. 3 and 4). Inside the housing body 20, a biasing member positioning boss 202 for positioning the biasing member 4 is provided (see Figs. 3 and 4).

[0027] The housing body 20 is provided on its outer surface with pins 203 and 204 that can be fitted to peripheral members of the switch device 1A (see FIG. 1).

[0028] The cover portion 21 prevents foreign matter such as water and dust from entering the housing body 20, and is made of an elastic body such as rubber that has excellent properties such as waterproofness, dustproofness, flexibility, etc. The cover portion 21 elastically deforms in accordance with the movement of the pushed-in member 3.

[0029] The cover fixing portion 22 is formed in a U-shape (approximately a U-shape) that opens downward (-Z direction) (see FIG. 1). A through hole 220 is provided in the center of the cover fixing portion 22 to allow the pushed-in member 3 to protrude to the outside of the housing 2. In the first embodiment, locking portions 221 that are locked to the locked portions 200 of the housing main body 20 are provided at both ends of the cover fixing portion 22.

[0030] <Push-in part> FIG. 5 is a schematic diagram showing an example of the sliding portion 31 in the first embodiment. The pressed member 3 moves in the moving direction D from the reference position to the pressed position when it is pressed from the outside, and returns to the reference position when it is released from the pressure. The "pressure from the outside" includes, for example, pressure received by the operation of a peripheral member of the switch device 1A. The "reference position" refers to the position of the pressed member 3 when it is not pressed from the outside. The "pressed position" refers to the position of the pressed member 3 that is the furthest from the reference position within the range in which the pressed member 3 can move when it is pressed from the outside. The "reference position" in the first embodiment is located above (to the side in the +Z direction) the "pressed position". The "pressed position" in the first embodiment refers to the position of the pressed member 3 when it hits the bottom surface of the housing main body 20 and further movement in the downward direction (-Z direction) is restricted.

[0031] The pressed member 3 has a button portion 30 and a sliding portion 31 (see FIGS. 2 and 3).

[0032] The button section 30 is a portion that receives pressure from the outside. The upper end of the button section 30 in the first embodiment is formed in a substantially quadrangular pyramid shape (see Figs. 1 to 3).

[0033] The sliding portion 31 is formed in the −X direction / +Z direction obliquely intersecting with the moving direction D, and is a portion that can slide on the movable contact portion 6. In the first embodiment, the sliding portion 31 is made slidable on the movable contact portion 6 by sliding the sliding portion 31 relative to the movable contact portion 6.

[0034] The sliding portion 31 in the first embodiment includes a first inclined surface 310 and a second inclined surface 311 formed stepwise in a direction obliquely intersecting with the moving direction D of the pressed member 3 on the inside of a leg portion 33 extending downward from the button portion 30 along the inner surface of the front surface of the housing 2 (see Figs. 3 and 5). The first inclined surface 310 is formed in a direction obliquely intersecting with the moving direction D of the pressed member 3 at an angle θ when viewed from the left-right direction (Y direction), and the second inclined surface 311 is formed above (to the side in the +Z direction) the first inclined surface in a direction obliquely intersecting with the moving direction D of the pressed member 3 at an angle φ smaller than the angle θ when viewed from the left-right direction (Y direction).

[0035] 3, a specific example in which the pressed member 3 in the first embodiment slides on the movable contact portion 6 at the sliding portion 31 will be described. As the pressed member 3 moves in the +D direction from the reference position to the pressed position, the sliding portion 31 of the pressed member 3 comes into contact with the movable contact portion 6 in the +D direction and slides on the movable contact portion 6. As described above, since the sliding portion 31 in the first embodiment is formed in the -X direction / +Z direction, the movable contact portion 6 slides on the sliding portion 31 in the -X direction / +Z direction relative to the pressed member 3 due to contact with the sliding portion 31 in the +D direction. In this manner, the pressed member 3 slides on the movable contact portion 6 at the sliding portion 31.

[0036] <Using member> The biasing member 4 biases the pushed member 3 toward a reference position, and is formed of, for example, a coil spring. The biasing member 4 is inserted into the biasing member positioning boss 202 of the housing body 20 (see Figs. 3 and 4). By providing the biasing member 4, the pushed member 3 returns to the reference position when the pushed member 3 is released from the pressure from the outside.

[0037] <Fixed contact part> The multiple fixed contact portions 5 in the first embodiment include a first fixed contact portion 5a and a second fixed contact portion 5b (see Figs. 2 and 4). The first fixed contact portion 5a and the second fixed contact portion 5b in the first embodiment both protrude from the lower portion of the housing body 20 and are capable of being electrically connected to peripheral members of the switch device.

[0038] The first fixed contact portion 5a is disposed on the right side (+Y direction side) within the housing body 20 (see Figs. 2 and 4). The second fixed contact portion 5b is disposed on the left side (-Y direction side) within the housing body 20 (see Figs. 2 and 4). A contacted portion 51 with which the movable contact portion 6 comes into contact is provided at the upper end portion of the second fixed contact portion 5b.

[0039] In addition, a resistor such as a chip resistor may be electrically connected between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0040] <Movable contact part> The movable contact portion 6 is provided to be swingable in a direction intersecting with the moving direction D of the pressed member 3, and switches the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b. "Switching the conductive state" refers to the operation of switching from a conductive state to an insulated state, or the reverse operation. The movable contact portion 6 in the first embodiment is electrically connected to the first fixed contact portion 5a, and is adapted to come into contact with and separate from the second fixed contact portion 5b to switch the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0041] The movable contact portion 6 in the first embodiment has an arm portion 60 and a contact portion 61 (see FIGS. 2 and 4).

[0042] The arm portion 60 in the first embodiment is open toward the center of the housing main body 20 and is formed in a U-shape (approximately a U-shape) in a plan view along the left-right direction (Y direction) (see FIG. 4). The first fixed contact portion 5a is electrically connected to the right end (+Y direction side) of the arm portion 60. As a specific example, the first fixed contact portion 5a is inserted into a slit 62 provided at the right end (+Y direction side) of the arm portion 60, thereby electrically connecting the arm portion 60 to the first fixed contact portion 5a (see FIG. 2).

[0043] The movable contact 6 is provided to be swingable in a swing direction S (+S / -S) along the front-rear direction (X direction) with the right (+Y direction) corner 65 of the U-shape of the arm 60 as a base end (see FIG. 4). The arm 60 functions as a leaf spring, and the movable contact 6 returns to its natural state when no load is applied.

[0044] The contact portion 61 (610, 611) in the first embodiment comes into contact with and separates from the second fixed contact portion 5b, and is formed by branching the left end (-Y direction side) of the arm portion 60 into a fork shape (see FIG. 4). The contact portion 61 (610, 611) is disposed so as to be separated from the second fixed contact portion 5b when the arm portion 60 is in an unloaded state (see FIGS. 2 to 4). Both the contact portion 610 and the contact portion 611 are formed in a U-shape that opens upward (+Z direction). The contact portion 611 is located inside the contact portion 610. The width of the contact portion 611, which is closer to the swing base end of the movable contact portion 6 than the contact portion 610, is set smaller than the width of the contact portion 610 (see FIG. 4). This makes it possible to equalize the frictional force between the contact portion 610 and the second fixed contact portion 5b and the frictional force between the contact portion 611 and the second fixed contact portion 5b, thereby making it possible for the contact portion 61 (610, 611) and the second fixed contact portion 5b to come into contact with and separate from each other smoothly.

[0045] Hereinafter, with reference to FIG. 4, a specific example in which the movable contact portion 6 in the first embodiment switches the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b will be described.

[0046] When the movable contact portion 6 in the first embodiment described above is pressed by the arm portion 60 in the -X direction, it swings in the +S direction with the corner portion 65 as the base end. The swing of the movable contact portion 6 in the +S direction causes the contact portion 61 of the movable contact portion 6, which had been separated from the second fixed contact portion 5b, to come into contact with the contacted portion 51 of the second fixed contact portion 5b. The movable contact portion 6, which is electrically connected to the first fixed contact portion 5a, comes into contact with the second fixed contact portion 5b, so that the first fixed contact portion 5a and the second fixed contact portion 5b are electrically connected to each other. When the movable contact portion 6 is released from the pressure in the -X direction and enters an unloaded state, it swings in the -S direction to return to its natural state. The swing of the movable contact portion 6 in the -S direction causes the contact portion 61 of the movable contact portion 6, which had been in contact with the second fixed contact portion 5b, to move away from the second fixed contact portion 5b. When the movable contact portion 6 electrically connected to the first fixed contact portion 5a is separated from the second fixed contact portion 5b, the first fixed contact portion 5a and the second fixed contact portion 5b are insulated from each other. In this manner, the movable contact portion 6 switches the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0047] As described above, since the movable contact portion 6 has multiple contact portions 61 (610, 611), even if a contact failure with the second fixed contact portion 5b occurs due to oxidation of the contact portion 610, for example, conductivity between the first fixed contact portion 5a and the second fixed contact portion 5b is ensured via the contact portion 611, thereby improving the contact reliability between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0048] In the first embodiment, the first fixed contact portion 5a and the second fixed contact portion 5b are both integrally formed with the housing body 20 by insert molding.

[0049] -Switch device operation- Next, the operation of the switch device 1A in the first embodiment will be described.

[0050] FIG. 6 is a side view and a plan view showing a state in which the first fixed contact portion 5a and the second fixed contact portion 5b in the first embodiment are insulated. FIG. 7 is a side view and a plan view showing a state in which the first fixed contact portion 5a and the second fixed contact portion 5b in the first embodiment are conductive. In the figure, the vertical dashed line indicates the sliding position of the pushed member 3 relative to the movable contact portion 6. In the figure, the horizontal dashed line conceptually indicates the reference position of the pushed member 3. In the figure, the hatched portion indicates the portion of the contact portion 61 of the movable contact portion 6 that contacts the second fixed contact portion 5b. These settings are the same in the following embodiments.

[0051] As shown in Figure 6, when the pushed member 3 is located at the reference position, the movable contact portion 6 is in an unloaded state, the contact portion 61 of the movable contact portion 6 is separated from the second fixed contact portion 5b, and the first fixed contact portion 5a and the second fixed contact portion 5b are insulated from each other.

[0052] When the pressed member 3 is pressed from the outside, the pressed member 3 is guided by the guide groove 201 of the housing 2 and moves in the +D direction toward the pressed position as shown in Fig. 7. As the pressed member 3 moves toward the pressed position, the sliding portion 31 slides toward the rear side (+X direction side) of the arm portion 60 of the movable contact portion 6. When the pressed member 3 slides on the arm portion 60 of the movable contact portion 6, the arm portion 60 slides on the sliding portion 31 in the -X direction / +Z direction relative to the pressed member 3 and is pressed by the sliding portion 31 along the -X direction. The movable contact portion 6 is swung in the +S direction, i.e., in a direction intersecting the moving direction D of the pressed member 3, by the pressure of the sliding portion 31 along the -X direction. As the movable contact portion 6 swings in the +S direction, the contact portion 61 of the movable contact portion 6 electrically connected to the first fixed contact portion 5a comes into contact with the contacted portion 51 of the second fixed contact portion 5b, establishing electrical continuity between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0053] When the pushed member 3 is released from the external pressure, the pushed member 3 moves in the -D direction as shown in Fig. 6 due to the biasing force of the biasing member 4 and returns to the reference position. The sliding of the pushed member 3 against the movable contact portion 6 is stopped, and the movable contact portion 6 is released from the pressure of the sliding portion 31 in the -X direction and swings in the -S direction. Due to the swinging of the movable contact portion 6 in the -S direction, the contact portion 61 of the movable contact portion 6 moves away from the second fixed contact portion 5b, and the first fixed contact portion 5a and the second fixed contact portion 5b are again insulated from each other.

[0054] As described above, when the pressed member 3 moves from the reference position toward the pressed position, the sliding of the pressed member 3 on the sliding portion 31 causes the movable contact portion 6 to be pressed by the sliding portion 31, causing the movable contact portion 6 to swing toward and away from the second fixed contact portion 5b, which is one of the multiple fixed contact portions 5 (5a, 5b), and switching the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0055] Here, when the angle at which the sliding part 31 intersects with the moving direction D of the pressed member 3 is ω, the ratio of the amount of movement of the pressed member 3 in the moving direction D and the amount of sliding of the movable contact part 6 on the sliding part 31 is approximately cos(ω):1. In addition, since the sliding part 31 is formed in the +sin(ω) direction / +cos(ω) direction, the movable contact part 6 slides on the sliding part 31 in the +sin(ω) direction / +cos(ω) direction relative to the pressed member 3, and is pressed by the sliding part 31 along the +sin(ω) direction to swing. That is, the ratio of the amount of movement of the pressed member 3 in the moving direction D and the amount of movement of the movable contact part 6 in the swing direction S is approximately 1:tan(ω). Therefore, the amount of movement of the movable contact part 6 in the swing direction S is necessarily smaller than the amount of movement of the pressed member 3 in the moving direction D. By reducing the amount of movement of the movable contact portion 6, the sliding distance that the movable contact portion 6 slides on the second fixed contact portion 5b after coming into contact with the second fixed contact portion 5b is also reduced, thereby reducing the amount of wear on the second fixed contact portion 5b and ultimately preventing a decrease in the contact reliability between the movable contact portion 6 and the second fixed contact portion 5b.

[0056] Of course, the shape of the sliding part 31 is not limited to the above and may be, for example, a flat surface, a curved surface, or an uneven surface, and in short, it may be a shape that can suppress the amount of movement in the oscillation direction S of the movable contact part 6 relative to the amount of movement in the movement direction D of the pressed member 3. The movement direction D of the pressed member 3 and the angle ω of the sliding part 31 obliquely intersecting with the movement direction D are not limited to the above example and may be, for example, one that changes depending on the amount of movement of the pressed member 3. Furthermore, the formation direction of the sliding part 31 is not limited to the above and may be, for example, the +X direction / +Z direction, or the Y direction / Z direction.

[0057] In the first embodiment, as described above, the sliding portion 31 includes the first inclined surface 310 and the second inclined surface 311 formed in a stepwise manner in a direction obliquely intersecting with the moving direction D of the pressed member 3, so that when the pressed member 3 moves from the reference position to the pressed position, the first inclined surface 310 of the sliding portion 31 slides against the movable contact portion 6, and as the member 3 moves, the second inclined surface 311 of the sliding portion 31 slides against the movable contact portion 6. The angles at which the first inclined surface 310 and the second inclined surface 311 intersect obliquely with the moving direction D of the pressed member 3 are angle θ and angle φ, respectively, so that the amount of movement of the movable contact portion 6 in the oscillation direction S changes according to the first inclined surface 310 and the second inclined surface 311. In this way, by making the sliding portion 31 include a plurality of inclined surfaces (first inclined surface 310 and second inclined surface 311) formed in stages in a direction obliquely intersecting the movement direction D of the pressed member 3, the amount of movement of the movable contact portion 6 in the oscillation direction S can be changed in accordance with the amount of movement of the pressed member 3 with a simple structure.

[0058] Furthermore, in the first embodiment, when the movable contact portion 6 contacts the second fixed contact portion 5b, the pressed member 3 slides on the movable contact portion 6 at the second inclined surface 311 of the sliding portion 31. As described above, the first inclined surface 310 is formed in a direction obliquely intersecting the moving direction D of the pressed member 3 at an angle θ, and the second inclined surface 311 is formed in a direction obliquely intersecting the moving direction D of the pressed member 3 at an angle φ smaller than the angle θ. When the ratio of the movement amount of the pressed member 3 in the moving direction D and the movement amount of the movable contact portion 6 in the swing direction S is applied, the ratio of the movement amount of the movable contact portion 6 in the swing direction S when it contacts the second fixed contact portion 5b and the movement amount of the movable contact portion 6 in the swing direction S when it is not in contact with any of the fixed contact portions 5 is approximately tan(φ):tan(θ). Therefore, the amount of movement of the movable contact portion 6 in the oscillation direction S when it is in contact with the second fixed contact portion 5b is smaller than the amount of movement of the movable contact portion 6 in the oscillation direction S when it is not in contact with any of the fixed contact portions 5. This reduces the sliding distance that the movable contact portion 6 slides on the second fixed contact portion 5b after coming into contact with the second fixed contact portion 5b, thereby reducing the amount of wear of the second fixed contact portion 5b and thereby reducing the deterioration of the contact reliability between the movable contact portion 6 and the second fixed contact portion 5b.

[0059] In the first embodiment, as described above, the sliding distance of the movable contact portion 6 on the second fixed contact portion 5b is reduced, which allows the switch device 1A to be reduced in size. Furthermore, in the first embodiment, as described above, the movable contact portion 6 has an arm portion 60 electrically connected to the first fixed contact portion 5a, which is one of the multiple fixed contact portions 5 (5a, 5b), and the arm portion 60 is pressed by the sliding portion 31 due to the sliding of the pressed member 3 on the sliding portion 31, so that the movable contact portion 6 swings to come into contact with or separate from the second fixed contact portion 5b, which is the other fixed contact portion. Since the movable contact portion 6 has the arm portion 60, the movable contact portion 6 can be provided to be swingable with a simple structure. Also, the sliding portion 31 of the pressed member 3 slides on the arm portion 60, so that the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b of the arm portion 60 can be switched with a simple structure in which the sliding of the sliding portion 31 is used to swing the movable contact portion 6.

[0060] Incidentally, from the viewpoint of corrosion resistance, it is desirable that the contacted portion 51 of the second fixed contact portion 5b with which the movable contact portion 6 comes into contact is coated with plating or the like. In the first embodiment, as described above, the sliding distance of the movable contact portion 6 on the second fixed contact portion 5b is reduced, which makes it possible to reduce the plated area of ​​the second fixed contact portion 5b, thereby contributing to a reduction in manufacturing costs.

[0061] As described above, the switch device 1A in the first embodiment is applicable to a normally open (NO) type switch.

[0062] (Embodiment 2) Hereinafter, a switching device 1B in the second embodiment will be described, focusing only on the differences from the first embodiment.

[0063] Fig. 8 is a see-through perspective view showing an example of the internal structure of the switch device 1B in embodiment 2. Fig. 9 is a plan view of the internal structure of the switch device 1B in Fig. 8 as viewed from above.

[0064] The contact portions 61 (610, 611) in the second embodiment are both disposed so as to come into contact with the contacted portion 51 of the second fixed contact portion 5b when the arm portion 60 is in an unloaded state.

[0065] Hereinafter, with reference to FIG. 9, a specific example in which the movable contact portion 6 in the second embodiment switches the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b will be described.

[0066] When the movable contact portion 6 in the second embodiment described above is pressed by the arm portion 60 in the -X direction, it swings in the +S direction. Due to the swing of the movable contact portion 6 in the +S direction, the contact portion 61 of the movable contact portion 6 that was in contact with the second fixed contact portion 5b moves away from the second fixed contact portion 5b. The movable contact portion 6 electrically connected to the first fixed contact portion 5a moves away from the second fixed contact portion 5b, so that the first fixed contact portion 5a and the second fixed contact portion 5b are insulated from each other. When the movable contact portion 6 is released from the pressure in the -X direction and is in an unloaded state, it swings in the -S direction to return to its natural state. Due to the swing of the movable contact portion 6 in the -S direction, the contact portion 61 of the movable contact portion 6 that was in contact with the second fixed contact portion 5b moves to contact the second fixed contact portion 5b. When the movable contact portion 6 electrically connected to the first fixed contact portion 5a comes into contact with the second fixed contact portion 5b, the first fixed contact portion 5a and the second fixed contact portion 5b are brought into a conductive state. In this manner, the movable contact portion 6 switches the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0067] Next, the operation of the switch device 1B in the second embodiment will be described.

[0068] Fig. 10 is a side view and a plan view showing a state in which the first fixed contact portion 5a and the second fixed contact portion 5b are conductive in embodiment 2. Fig. 11 is a side view and a plan view showing a state in which the first fixed contact portion 5a and the second fixed contact portion 5b are insulated in embodiment 2.

[0069] As shown in Figure 10, when the pushed-in member 3 is located at the reference position, the movable contact portion 6 is in an unloaded state, the contact portion 61 of the movable contact portion 6 is in contact with the contacted portion 51 of the second fixed contact portion 5b, and electrical continuity is established between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0070] When the pressed member 3 is pressed from the outside, it moves in the +D direction toward the pressed-in position as shown in Fig. 11. As the pressed member 3 moves toward the pressed-in position, the sliding portion 31 slides against the arm portion 60 of the movable contact portion 6. When the movable contact portion 6 slides away from the pressed member 3, it is pressed by the sliding portion 31 in the -X direction and swings in the +S direction. Due to the swinging of the movable contact portion 6 in the +S direction, the contact portion 61 of the movable contact portion 6 electrically connected to the first fixed contact portion 5a moves away from the second fixed contact portion 5b, and the first fixed contact portion 5a and the second fixed contact portion 5b are insulated from each other.

[0071] When the pushed member 3 is released from the external pressure, the pushed member 3 moves in the -D direction by the biasing member 4 as shown in Fig. 10 and returns to the reference position. The sliding of the pushed member 3 against the movable contact portion 6 is stopped, and the movable contact portion 6 is released from the pressure of the sliding portion 31 in the -X direction and swings in the -S direction. Due to the swinging of the movable contact portion 6 in the -S direction, the contact portion 61 of the movable contact portion 6 comes into contact with the contacted portion 51 of the second fixed contact portion 5b, and electrical continuity is restored between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0072] As described above, the switch device 1B in the second embodiment is applicable to a normally closed (NC) type switch.

[0073] (Embodiment 3) Hereinafter, a switching device 1C in the third embodiment will be described, focusing only on the differences from the first embodiment.

[0074] Fig. 12 is a see-through perspective view showing an example of the internal structure of the switch device 1C in embodiment 3. Fig. 13 is a side view of the internal structure of the switch device 1C in Fig. 12 viewed from the left. Fig. 14 is a plan view of the internal structure of the switch device 1C in Fig. 12 viewed from above.

[0075] The switch device 1C in embodiment 3 includes a housing 2, a pushed member 3, a biasing member 4, a fixed contact portion 5 (5a, 5b), and a pair of opposing movable contact portions 6a and 6b (see FIG. 12).

[0076] The pressed member 3 in the third embodiment has a sliding portion for each of the movable contact portion 6a and the movable contact portion 6b. Specifically, the pressed member 3 has a sliding portion 31a that can slide on the movable contact portion 6a, and a sliding portion 31b that can slide on the movable contact portion 6b (see FIG. 13). The sliding portion 31a is formed in the -X direction / +Z direction on the inner side of the leg portion 33a that extends downward from the button portion 30 along the inner surface of the front of the housing 2, and the sliding portion 31b is formed in the +X direction / +Z direction on the inner side of the leg portion 33b that extends downward from the button portion 30 along the inner surface of the back of the housing 2 (see FIG. 13).

[0077] Hereinafter, with reference to FIG. 13, a specific example of the sliding of the pressed member 3 on the movable contact portion 6a and the movable contact portion 6b at the sliding portion 31a and the sliding portion 31b in the third embodiment will be described. When the pressed member 3 moves in the +D direction from the reference position to the pressed position side, the sliding portion 31a of the pressed member 3 comes into contact with the movable contact portion 6a in the +D direction and slides on the movable contact portion 6a. At this time, the movable contact portion 6a slides on the sliding portion 31a in the -X direction / +Z direction relative to the pressed member 3. Similarly, the sliding portion 31b comes into contact with the movable contact portion 6b in the +D direction and slides on the movable contact portion 6b. At this time, the movable contact portion 6b slides on the sliding portion 31b in the +X direction / +Z direction relative to the pressed member 3.

[0078] In the third embodiment, the first fixed contact portion 5a has an upper end provided with a contacted portion 51a with which the movable contact portion 6b comes into contact, and the second fixed contact portion 5b has an upper end provided with a contacted portion 51b with which the movable contact portion 6a comes into contact (see FIGS. 12 and 14).

[0079] In embodiment 3, the movable contact portion 6a and the movable contact portion 6b are electrically connected to the first fixed contact portion 5a and the second fixed contact portion 5b, respectively, and are adapted to come into contact with and separate from each other to switch the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0080] The movable contact portion 6a in the third embodiment has an arm portion 60a and a contact portion 61a, and the movable contact portion 6b has an arm portion 60b and a contact portion 61b (see FIGS. 12 and 14). The first fixed contact portion 5a is electrically connected to the right end (+Y direction side) of the arm portion 60a of the movable contact portion 6a. The second fixed contact portion 5b is electrically connected to the left end (-Y direction side) of the arm portion 60b of the movable contact portion 6b (see FIGS. 12 and 14).

[0081] The movable contact 6a is provided to be able to swing in a swing direction S1 (+S1 / -S1) along the front-rear direction (X direction) with a right (+Y direction) corner 65a of the U-shape of the arm 60a as a base end (see FIG. 14). Similarly, the movable contact 6b is provided to be able to swing in a swing direction S2 (+S2 / -S2) along the front-rear direction (X direction) with a left (-Y direction) corner 65b of the U-shape of the arm 60b as a base end (see FIG. 14).

[0082] The contact portion 61a is disposed so as to be spaced apart from the second fixed contact portion 5b when the arm portion 60a is in an unloaded state. Similarly, the contact portion 61b is disposed so as to be spaced apart from the first fixed contact portion 5a when the arm portion 60b is in an unloaded state.

[0083] Hereinafter, with reference to FIG. 14, a specific example in which the movable contact portion 6a and the movable contact portion 6b in the third embodiment switch the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b will be described.

[0084] When the movable contact portion 6a in the first embodiment described above is pressed by the arm portion 60a in the -X direction, it swings in the +S1 direction with the corner portion 65a as the base end. Similarly, when the movable contact portion 6b is pressed by the arm portion 60b in the +X direction, it swings in the +S2 direction with the corner portion 65b as the base end. Due to the swing of the movable contact portion 6a in the +S1 direction, the contact portion 61a of the movable contact portion 6a that was separated from the second fixed contact portion 5b comes into contact with the contacted portion 51b of the second fixed contact portion 5b, and due to the swing of the movable contact portion 6b in the +S2 direction, the contact portion 61b of the movable contact portion 6b that was separated from the first fixed contact portion 5a comes into contact with the contacted portion 51a of the first fixed contact portion 5a. The first fixed contact portion 5a and the second fixed contact portion 5b come into contact with each other, resulting in a state in which the first fixed contact portion 5a and the second fixed contact portion 5b are electrically connected to each other. Also, when the movable contact portion 6a is released from the pressure in the -X direction and is in an unloaded state, it swings in the -S1 direction to return to its natural state. Similarly, when the movable contact portion 6b is released from the pressure in the +X direction and is in an unloaded state, it swings in the -S2 direction to return to its natural state. Due to the swing of the movable contact portion 6a in the -S1 direction, the contact portion 61a of the movable contact portion 6a that was in contact with the second fixed contact portion 5b moves away from the second fixed contact portion 5b, and due to the swing of the movable contact portion 6b in the -S2 direction, the contact portion 61b of the movable contact portion 6b that was in contact with the first fixed contact portion 5a moves away from the first fixed contact portion 5a. The first fixed contact portion 5a and the second fixed contact portion 5b move away from each other, resulting in an insulated state between the first fixed contact portion 5a and the second fixed contact portion 5b. In this way, the movable contact portion 6 switches the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0085] As described above, since the switch device 1C has a plurality of movable contact portions (movable contact portion 6a and movable contact portion 6b), even if a contact failure occurs between the first fixed contact portion 5a and the second fixed contact portion 5b due to oxidation of the movable contact portion 6a, for example, conduction between the first fixed contact portion 5a and the second fixed contact portion 5b is ensured via the movable contact portion 6b, thereby improving the contact reliability between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0086] Next, the operation of the switch device 1C in the third embodiment will be described.

[0087] Fig. 15 is a side view and a plan view showing a state in which the first fixed contact portion 5a and the second fixed contact portion 5b are insulated from each other in embodiment 3. Fig. 16 is a side view and a plan view showing a state in which the first fixed contact portion 5a and the second fixed contact portion 5b are in conduction from each other in embodiment 3.

[0088] As shown in Figure 15, when the pushed-in member 3 is located at the reference position, both the movable contact portion 6a and the movable contact portion 6b are in an unloaded state, the movable contact portion 6a and the movable contact portion 6b are separated from each other, and the first fixed contact portion 5a and the second fixed contact portion 5b are insulated from each other.

[0089] When the pushed member 3 is pressed from the outside, the pushed member 3 is guided by the guide groove 201 of the housing 2 and moves to the pushed position side in the +D direction as shown in FIG. 16. As the pushed member 3 moves to the pushed position side, the sliding part 31a slides toward the rear side (+X direction side) of the arm part 60a of the movable contact part 6a, and the sliding part 31b slides toward the front side (-X direction side) of the arm part 60b of the movable contact part 6b. When the pushed member 3 slides on the arm part 60a of the movable contact part 6a, the arm part 60a slides on the sliding part 31a in the -X direction / +Z direction relative to the pushed member 3, and is pressed by the sliding part 31a along the -X direction. The movable contact part 6a swings in the +S1 direction due to the pressure of the sliding part 31a along the -X direction. Similarly, when the pushed member 3 slides on the arm portion 60b of the movable contact portion 6b, the arm portion 60b slides on the sliding portion 31b in the +X direction / +Z direction relative to the pushed member 3 and is pressed in the +X direction by the sliding portion 31b. The movable contact portion 6b swings in the +S2 direction due to the pressure of the sliding portion 31b in the +X direction.

[0090] Due to the swinging of the movable contact portion 6a in the +S1 direction and the swinging of the movable contact portion 6b in the +S2 direction, the contact portion 61a of the movable contact portion 6a comes into contact with the contacted portion 51b of the second fixed contact portion 5b, and the contact portion 61b of the movable contact portion 6b comes into contact with the contacted portion 51a of the first fixed contact portion 5a. In other words, the first fixed contact portion 5a and the second fixed contact portion 5b come into contact with each other, and the first fixed contact portion 5a and the second fixed contact portion 5b are in electrical contact with each other.

[0091] When the pressed member 3 is released from the pressure from the outside, the pressed member 3 moves in the -D direction by the biasing member 4 as shown in FIG. 15 and returns to the reference position. The sliding of the pressed member 3 against the movable contact portion 6 is stopped, and the movable contact portion 6a is released from the pressure of the sliding portion 31a in the -X direction and swings in the -S1 direction. Similarly, the movable contact portion 6b is released from the pressure of the sliding portion 31b in the +X direction and swings in the -S2 direction. Due to the swinging of the movable contact portion 6 in the -S1 direction and the swinging of the movable contact portion 6b in the -S2 direction, the first fixed contact portion 5a and the second fixed contact portion 5b are separated from each other, and the first fixed contact portion 5a and the second fixed contact portion 5b are again insulated from each other.

[0092] As described above, in embodiment 3, the pushed-in member 3 has a sliding portion for each of the multiple movable contact portions (movable contact portion 6a and movable contact portion 6b), making it possible to oscillate each of the multiple movable contact portions (movable contact portion 6a and movable contact portion 6b), thereby improving the design freedom of the switch device 1C.

[0093] Furthermore, as described above, the switch device 1C has a pair of movable contact portions 6a and 6b, and the pressed member 3 has a pair of sliding portions 31a and 31b relative to the pair of movable contact portions 6a and 6b. As the pressed member 3 moves from the reference position toward the pressed position, the pair of sliding portions 31a and 31b slide against the movable contact portions 6a and 6b, respectively, in a balanced manner, thereby improving the stability of the pressed member 3 when it is pressed.

[0094] As described above, the switch device 1C in the third embodiment is applicable to a normally open (NO) type switch.

[0095] (Embodiment 4) The following describes the switch device in the fourth embodiment, focusing only on the differences from the first embodiment.

[0096] Fig. 17 is a plan view showing a schematic state in which the first fixed contact portion 5a and the second fixed contact portion 5b are electrically connected in embodiment 4. Fig. 18 is a plan view showing a schematic state in which the first fixed contact portion 5a and the third fixed contact portion 5c are electrically connected in embodiment 4.

[0097] The fixed contact portion 5 in the fourth embodiment includes a first fixed contact portion 5a, a second fixed contact portion 5b, and a third fixed contact portion 5c (see FIGS. 17 and 18). The second fixed contact portion 5b has a contacted portion 51b arranged on the left side (-Y direction side) in the housing main body 20, and the third fixed contact portion 5c has a contacted portion 51c arranged in front of (-X direction lateral side) the contacted portion 51b of the second fixed contact portion 5b (see FIGS. 17 and 18).

[0098] The movable contact portion 6 in embodiment 4 is electrically connected to the first fixed contact portion 5a, and is adapted to move in and out of contact with the second fixed contact portion 5b and the third fixed contact portion 5c to switch the conductive state between the second fixed contact portion 5b and the third fixed contact portion 5c.

[0099] The contact portion 61 in the fourth embodiment is disposed so as to come into contact with the second fixed contact portion 5b when the arm portion 60 is in an unloaded state.

[0100] Hereinafter, with reference to Figs. 17 and 18, a specific example in which the movable contact portion 6 in the fourth embodiment switches the conductive state between the second fixed contact portion 5b and the third fixed contact portion 5c will be described.

[0101] When the movable contact portion 6 in the fourth embodiment described above is pressed by the arm portion 60 in the -X direction, it swings in the +S direction. Due to the swing of the movable contact portion 6 in the +S direction, the contact portion 61 of the movable contact portion 6 that was in contact with the second fixed contact portion 5b moves away from the second fixed contact portion 5b and comes into contact with the contacted portion 51c of the third fixed contact portion 5c (see FIG. 18). The movable contact portion 6 electrically connected to the first fixed contact portion 5a moves away from the second fixed contact portion 5b and comes into contact with the third fixed contact portion 5c, so that the first fixed contact portion 5a and the second fixed contact portion 5b are insulated from each other, and the first fixed contact portion 5a and the third fixed contact portion 5c are in a conductive state. When the movable contact portion 6 is released from the pressure in the -X direction and goes into an unloaded state, it swings in the -S direction to return to its natural state. By the swing of the movable contact portion 6 in the -S direction, the contact portion 61 of the movable contact portion 6 that was in contact with the third fixed contact portion 5c moves away from the third fixed contact portion 5c and comes into contact with the contacted portion 51b of the second fixed contact portion 5b (see FIG. 17). The movable contact portion 6 electrically connected to the first fixed contact portion 5a moves away from the third fixed contact portion 5b and comes into contact with the second fixed contact portion 5b, so that the first fixed contact portion 5a and the second fixed contact portion 5b are in a conductive state and the first fixed contact portion 5a and the third fixed contact portion 5c are insulated from each other. In this way, the movable contact portion 6 switches the conductive state between the first fixed contact portion 5a and the second fixed contact portion 5b.

[0102] As described above, the switch device in the fourth embodiment is applicable to a double-throw switch.

[0103] Although a single-pole switch has been described as an example in the above first to fourth embodiments, the switch device described in the present application can also be applied to a multi-pole switch.
