According to the invention, the retaining element (160) is connected to the base (110).

Description

Technical Field

[0001] This invention generally relates to the field of electrical switches.

[0002] More specifically, the present invention relates to a mechanism for an electrical switch, comprising:

[0003] -Base;

[0004] - A drive element, which is mounted in the base to flip (oscillate) between two positions so that the movable contact element contacts or disengages from the fixed contact element;

[0005] - A compressible element that can move between two configurations, including a non-active configuration and a movable configuration, in which the compressible element is inactive relative to the drive member, allowing the drive member to freely take either of the two positions; in the movable configuration, the compressible element is received between the support surface of the base and the drive member, and forces the drive member to return to a stable position of the two positions.

[0006] - A retaining element for holding a compressible element in the inactive configuration, in which the compressible element does not engage with the retaining element and can move along the displacement axis between the support surface and the drive member, and in the inactive configuration, the compressible element engages with the retaining element to lock (lock, prevent) this mobility. Background Technology

[0007] A mechanism for an electrical switch is known in particular from the applicant's document FR3060197. However, in this mechanism, the holding element consists of an additional component dedicated to the remainder of the base and movable relative to it. The presence of this additional component increases the complexity of the electrical switch—particularly in terms of its manufacturing and usage methods—and also adds to its clutter. Summary of the Invention

[0008] Therefore, the object of the present invention is to provide a novel structure for electrical switches, which has a simplified structure and operation mode, and reduces the degree of clutter.

[0009] More specifically, according to the present invention, a mechanism as described in the technical field section is provided, wherein the retaining element is fixed on the base.

[0010] Therefore, advantageously according to the invention, the retaining element consists of a fixed, immovable component. It is integrated into the base in a manner that does not increase the overall clutter of the base.

[0011] Other non-limiting and advantageous technical features of the apparatus according to the invention—features that can be applied individually or in combination in a technically possible manner—are as follows:

[0012] - The retaining element is formed together with the base;

[0013] - The retaining element is a rigid, non-deformable element of the base;

[0014] - The retaining element includes a retaining surface of the base wall, and the compressible element includes a complementary latching (hooking) surface adapted to abut against the retaining surface of the base wall to lock the compressible element in the inactive configuration;

[0015] - The retaining element includes a recessed portion or window in the wall of the base, partially defined by the retaining surface;

[0016] - The compressible element includes a compression spring and a cap accommodating the compression spring, the cap including the complementary locking surface;

[0017] - The complementary locking surface belongs to at least one fixed pin that extends from the side wall of the cap toward the outside of the cap;

[0018] - The cap rotates to transition from one of the active and inactive configurations to the other;

[0019] - The complementary locking surface is a locking tooth that extends outward from the clamping claw cut into the side wall of the cap;

[0020] - The cap of the compressible element performs a translational movement to transition from one of the active and inactive configurations to the other;

[0021] - The compressible element is housed in a cavity of the base, which is located below the drive element and is defined by a sidewall including the retaining element;

[0022] - The front wall of the drive unit located above the compressible element includes a through opening through which the compressible element can be accessed (operated, touched) from the front side of the mechanism for electrical switching;

[0023] - The compressible element includes a compression spring and a cap that houses the compression spring. The cap rotates to transition from one of the active configuration to the other of the inactive configuration. The head of the cap is equipped with a slit for receiving the tool tip. A through opening in the front wall of the drive element has a shape adapted to restrict the rotational movement of the tool tip at a predetermined angle.

[0024] The present invention also relates to an electrical switch assembly for an electrical switch, comprising the mechanism as described above and a control contact associated with a drive element of the mechanism.

[0025] The present invention also relates to an electrical switch comprising such an electrical switch assembly and a housing or mounting frame that at least partially accommodates the mechanism.

[0026] Finally, the present invention relates to a sealed electrical switch, wherein a decorative panel is provided, which seals the housing or mounting frame for accommodating the aforementioned mechanism, and each control contact belongs to the decorative panel. Attached Figure Description

[0045] As a premise, it should be noted that the same or similar elements of the invention shown in each of the accompanying drawings in different embodiments will be marked with the same reference numerals and will not be described every time.

[0046] In the following description, the terms "front" and "back" are used relative to the user's line of sight to the wall to which the electrical switch, including the mechanism according to the invention, is attached. Therefore, when the electrical switch is installed in a room, "front" refers to the side facing inwards, and "back" refers to the opposite side, facing outwards, i.e., towards the interior of the wall. The front side is also the side facing the user.

[0047] Figures 1 to 16 Two possible embodiments of the dual mechanism 100; 200 for electrical switches according to the present invention are shown.

[0048] The dual mechanism comprises two mechanisms 100 and 200 according to the invention.

[0049] Each mechanism according to the invention can be of any type and is externally actuated by a control contact (not shown). It can be a circuit breaker or a double-circuit switch.

[0050] The electrical switch shown here includes a housing (box, case) 20 (see Figure 11 The housing 20 accommodates the mechanisms 100 and 200. The housing 20 is intended to be attached to a wall in a projecting mounting manner. In a variant, the electrical switch may also include a recessed frame intended to be attached to an electrical housing embedded in the wall. It also includes a drive element 126 or 226 (see [link to relevant documentation]) adapted to actuate the mechanisms 100 and 200. Figure 1 , 2 The control touchpads (not shown) for 14 to 16).

[0051] Mechanisms 100 and 200 for electrical switches are connected to the power grid to supply power to them.

[0052] Additionally, advantageously, the electrical switches shown in the figures are sealed switches, wherein the decorative panel (not shown) to which each control contact belongs is sealed to the housing 20 or mounting frame that houses each mechanism 100; 200.

[0053] It should be noted that, here, the electrical switch is equipped with a single base 110; 210 for both mechanisms 100; 200 (see... Figure 1 , 9 10, 12, 15, and 16). The base 110; 210 accommodates all electrical connection terminals 130; 230 and receives the two actuators 126; 226 of the two mechanisms 100; 200 (see...). Figure 2 , 9 13, 15).

[0054] Of course, according to variations not shown, the base can also be designed to receive a single drive element belonging to the mechanism.

[0055] The bases 110 and 210 form an insulating enclosure, which is made of, for example, molded plastic material.

[0056] The bases 110 and 210 have a generally parallelepiped shape and have a front wall 111A and 211A and an opposite rear wall 111B and 211B. The front and rear walls are connected by side walls 111C, 111D; 211C, 211D (see...). Figure 2 and 13 Here, the base 110; 210 is formed by assembling two parts: the front part 110A; 210A and the rear part 110B; 210B (see...). Figure 2 and 13 ).

[0057] The rear portion 110B of the base 110; 210B includes a plurality of inner walls 112; 212 (see Figure 2 and 13 These inner walls rise from the rear walls 111B and 211B toward the front walls 111A and 211A, defining spaced-apart cavities suitable for receiving electrical connection terminals 130 and 230 (see...). Figure 1 and 12 ).

[0058] Advantageously, here, base 110; 210 includes six cavities spaced apart from each other for accommodating three or six electrical connection terminals—depending on whether it is a single or double mechanism. Thus, advantageously, base 110; 210 is identical to an electrical switch including one or two control contacts.

[0059] Here, mechanisms 100 and 200 are equipped with six electrical connection terminals 130 and 230, three of which form a first circuit of the mechanism, and the other three form a second circuit of another mechanism, which is independent of the first circuit (see...). Figure 2 and 13 ).

[0060] The front portions 110A and 210A of the base 110 and 210 close the rear portions 110B and 210B at the front to constrain the conductive components housed in the base 110 and 210, particularly the electrical connection terminals 130 and 230 connected to the local power grid.

[0061] The front portion 110A of the base 110; 210A also includes at least one access channel 114; 214 that allows access to one of the electrical connection terminals 130; 230 housed in the base 110; 210 (see Figure 1 , 2 (1, 2, and 13). Preferably, the front portion 110A; 210A of the base 110; 210 includes one or two access channels through which each electrical connection terminal 130; 230 housed in the base 110; 210 can be accessed (touched, operated) via the access channels.

[0062] Each access channel 114; 214 is defined by the inner surface of an aperture leading to the front surface of the front wall 111A; 211A of the base 110; 210. Each access channel 114; 214 is adapted for the stripped end of an electrical wire to pass through for electrical connection with a corresponding electrical connection terminal 130; 230.

[0063] Here, the bases 110 and 210 also include mounting elements at their four corners (see...). Figure 1 , 2 110, 210, and 12, 13, are used for mounting the base 110 in the protruding housing 20 (which is itself attached to the wall). Preferably, these mounting elements allow the base 110; 210 to be mounted in the housing 20 in at least two mutually perpendicular directions.

[0064] When the bases 110 and 210 are installed in the housing 20, the bases 110 and 210 are intended to abut against the support plane PS located at the rear of the base (see...). Figure 1 ).

[0065] Here, the mounting elements are in the form of mounting claws (ears) 113; 213, which extend laterally at the four corners of the base 110; 210 (see...). Figure 3 More specifically, they extend along a plane parallel to the supporting plane PS (see...). Figure 1 and 12 The support plane PS is generally parallel to the front wall 111A; 211A and the rear wall 111B; 211B of the base 110; 210.

[0066] Here, the four mounting claws 113; 213 are centrally symmetrical with respect to the center of the base 110; 210. They extend along the diagonal direction of the base 110; 210 and are equidistant from each other. Each mounting claw 113; 213 includes an aperture for a retaining screw to pass through (see...). Figure 1 and 12 ).

[0067] Each mounting claw 113; 213 is adapted to abut against the front end of the receiving tube (well-shaped portion) 21 rising from the bottom wall of the housing 20, such that the orifice of each mounting claw 113; 213 coincides with the central orifice of the corresponding receiving tube 21 (see...). Figure 11 Each mounting claw 113; 213 is thus secured to the corresponding receiving tube 21 by tightening each fixing screw.

[0068] Here, the end of the receiving cylinder 21 of the housing 20 embodies the support plane PS defined above (see above). Figure 11 ).

[0069] In a variation, the mounting element may include an equipment support having the form of a frame surrounding a base. The equipment support may be integral with the base, or it may be a separate component—the base being attached to the equipment support. In this case, the equipment support and the base comprise complementary assembly arrangements.

[0070] Similarly, in variations, the base includes, for example, resilient snap-fit ​​claws designed to engage with complementary portions of the housing or mounting frame via a snap-fit ​​mechanism.

[0071] Electrical connection terminals 130 and 230 are, for example, automatic connection terminals.

[0072] More specifically, such as Figure 2 and 13 As shown, each electrical connection terminal 130; 230 is made by cutting and shaping a metal strip. Each electrical connection terminal 130; 230 includes a bracket 130A; 230A and a leaf spring 130B; 230B extending abutting against the bracket 130A; 230A.

[0073] Here, each conductive bracket 130A; 230A has two planar regions connected to each other by a bridging portion. An opening in the bridging portion allows the stripped end of the wire to pass through. The free end of the leaf spring 130B; 230B points towards the contact area formed by a portion of the inner surface of the bracket 130A; 230A, while the other end of the leaf spring 130B; 230B abuts against the bracket 130A; 230A through the lateral crease 130C; 230C of the bracket 130A; 230A (see...). Figure 2 and 13 ).

[0074] In order to make an electrical connection with one of the electrical connection terminals 130; 230, the stripped end of a wire (not shown) originating from the power grid is inserted into the bracket 130A; 230A of the electrical connection terminal via an access channel 114; 214 provided in the front portion 110A; 210A of the base 110; 210 of the mechanism 100; 200, such that the exposed conductor core of the wire is engaged between the inner surface of the bracket 130A; 230A and the free end of the leaf spring 130B; 230B.

[0075] Leaf springs 130B and 230B are prestressed so that, under the action of a wire inserted into the bracket, the leaf springs move away from the contact area and apply sufficient pressure to the exposed metal core of the wire, thereby establishing good contact between the electrical terminal and the metal core of the wire, while preventing the wire from being accidentally pulled manually out of the bracket (the clamping force applied by the leaf springs must be sufficient to resist the standard pull-out force applied to the wire).

[0076] To remove the wire from the electrical terminals 130; 230, an operable push plate (not shown) is provided in a manner known per se, which passes through an opening 131; 231 formed in the front portion 110A; 210A of the base 110; 210 of the mechanism 100; 200 (see...). Figure 1 , 21, 2, and 3) are used to actuate the operating portion of the leaf spring 130B; 230B of the electrical connection terminals 130; 230, thereby separating the leaf spring 130B; 230B from the wire. The wire, no longer controlled by the leaf spring 130B; 230B, can be easily pulled out of the mechanism 100; 200.

[0077] Typically, to define the circuit, each control touchpad is associated with three electrical connection terminals 130; 230 by means of each actuator 126; 226. Of the three electrical connection terminals, as in the example shown here, two electrical connection terminals 130; 230 include fixed contact elements.

[0078] More specifically, here, the brackets 130A and 230A of the two electrical connection terminals 130 and 230 are extended by end portions equipped with fixed contact points 132 and 232 (see...). Figure 2 and 13 ).

[0079] The third electrical connection terminal 130; 230 is connected to the fixed clamping plate 123; 223 via a conductive sheet, and is referred to as the movable part of the brush 124; 224, which is pivotally mounted on the clamping plate 123; 223 and received by the clamping plate 123; 223 (see...). Figure 2 , 9 10 and 13, 15, 16).

[0080] The clamping plates 123 and 223 are V-shaped profiles. These profiles are substantially parallel to the support plane PS located behind the bases 110 and 210 (see...). Figure 1 , 9 (10, 13, 15, 16) extends. Its longitudinal axis is defined by brushes 124; 224 defines the pivot axis A1; B1 (see Figure 1 , 9 10, 13, 15, 16).

[0081] Each brush 124; 224 is an L-shaped sheet, one branch of which is received on the side by a clamping plate 123; 223 for establishing electrical contact, and the other branch carries a movable contact point 124A; 224A (see Figure 2 and 13 ).

[0082] By utilizing the displacement of each drive element 126; 226, each brush 124; 224 is adapted to pivot between two extreme positions about the pivot axis A1; B1 for a movable contact element—in this case, in the form of a movable contact point 124A; 224A carried by the brush 124; 224—to contact or disengage from at least one fixed contact point 132; 232 carried by the fixed element of the electrical connection terminal 130; 230 (see...) Figure 9 , 10 15, 16).

[0083] Each drive element 126; 226 is associated with a single control device, and therefore with a single circuit.

[0084] Here, the drive element 126; 226 is pivotally mounted on the base 110; 210 about the flip axis, thereby causing the brush 124; 224 to displace between its two extreme positions.

[0085] For example, it is reversibly mounted by means of two trunnions formed on the drive members 126; 226 and respectively engaging in two corresponding orifices 126A; 226A formed in the bases 110; 210, thereby defining a reversing axis A2; B2 for the drive members 126; 226 (see Figure 2 and 13 The rotating axes A2 and B2 are substantially parallel to the pivoting axes A1 and B1 of the associated brushes 124 and 224.

[0086] Here, each drive element 126; 226 is adapted to displace the corresponding brush 124; 224 between a first extreme position and another extreme position, in which the movable contact 124A; 224A contacts the fixed contact 132; 232, and in the other extreme position, the movable contact 124A; 224A contacts the other fixed contact 132; 232.

[0087] In a variant, each drive element can be adapted to displace the corresponding brush between a position in which the movable contact point is in contact with the fixed contact point and another position in which the movable contact point is out of contact with the fixed contact point.

[0088] Each drive element 126; 226 is an insulating component, for example, made of molded plastic material.

[0089] Each drive element 126; 226 includes a front wall 128; 228 extending on either side of its flip axis A2; B2 located in front of the base 110; 210. It extends rearwardly via tubular elements 127; 227 (see...). Figure 9 , 10 15 and 16).

[0090] Here, the front wall 128; 228 of each drive element 126; 226 has a standard width referred to as "a module".

[0091] In the variant, the width of the drive element can be twice the standard width, or the width referred to as "two modules".

[0092] Tubular elements 127 and 227 are integrally formed with drive members 126 and 226 (here, they form a single component with drive members 126 and 226), extending rearward perpendicularly to drive members 126 and 226 at the axis of rotation, and passing through an opening provided in the front portion 110A and 210A of the base 110 and 210 for this purpose between the inner walls 112 and 212 of the rear portions 110B and 210B of the base 110 and 210 (see...). Figure 9 , 10 15 and 16).

[0093] It also features, in a conventional manner, a spring-loaded reversing device 129; 229 for each of the brushes 124; 224 (see...). Figure 2 , 9 (10 and 13, 15, 16). Typically, the resilient flipping device 129; 229 includes a spring mounted in a tubular element 127; 227 associated with the brush 124; 224, and is adapted to drive the brush 124; 224 toward one or another extreme position depending on the position of the drive member 126; 226 after passing the hard point.

[0094] For this purpose, each brush 124 224 received in the clamping plate 123 223 has a protrusion 125 225 on the opposite side of its side that contacts the clamping plate 123 223, forming a spring for a spring-loaded elastic flipping device 129 229 (see [link to relevant documentation]). Figure 2 and 13 The movement of each drive element 126; 226 drives the movement of the spring, thereby driving the movement of the corresponding brush 124; 224.

[0095] Therefore, by operating a touchpad (not shown) connected to each of the drive elements 126; 226, the user controls each drive element 126; 226 to flip toward one of its positions, thereby driving the resilient flipping device 129; 229 to flip and driving the associated brush 124; 224 to flip, so that the movable contact element 124A; 224A contacts or disengages from the fixed contact element 132; 232. The two positions of each drive element 126; 226 correspond to the two extreme positions of the brush 124; 224.

[0096] Therefore, the movement of each drive element 126; 226 drives the movement of the spring, which in turn drives the movement of the brush 124; 224 so that the brush 124; 224 flips rapidly and accurately between two extreme positions while avoiding the formation of an electric arc.

[0097] Therefore, advantageously, in the case of a single control device, the same base has a mounting device that can accommodate a single drive element, and in the case of a dual control device, the same base has a mounting device that can accommodate two different drive elements. Thus, a single universal base suitable for either a single-control configuration or a dual-control configuration of the electrical switch according to the invention can be manufactured.

[0098] For each mechanism 100; 200, the base 110; 210 forms a receiving tube 115; 215 of the compressible element 150; 250 (see...). Figure 2 , 13 Here, the receiving cylinder 115; 215 is at least partially defined by a cylindrical wall. It forms a cavity for receiving the compressible element 150; 250, which is located below the front wall of the drive element 126; 226, that is, at the rear of the front wall.

[0099] Here, the compressible element 150; 250 includes a spring 152; 252 and a cap 154; 254 (see [link to cap]) slidably mounted relative to the receiving cylinder 115; 215 along the compression axis of the spring 152; 252. Figure 2 and 13 ).

[0100] The cap 154; 254 has a cylindrical body 154A; 254A and a head 155; 255. Here, the body 154A; 254A of the cap 154; 254 is primarily formed by cylindrical sidewalls. The end of the body 154A; 254A opposite to the head 155; 255 is open. The body 154A; 254A is hollow and is used to house the spring 152; 252. The spring is compressed and received between the support plane of the base 110; 210—here, the bottom of the receiving cylinder 115; 215 of the base 110; 210—and the head 155; 255 of the cap 154; 254.

[0101] The compressible element 150; 250 of each mechanism 100; 200 can move between two configurations, one of which is an inactive configuration in which it is inactive relative to the drive element 126; 226, allowing the drive element 126; 226 to be freely positioned in one of the two positions of the drive element (see...). Figure 9 and 16 Another configuration is a movable configuration, in which it is received between the support surface of the base 110; 210 and the drive member 126; 226, and constrained by the drive member 126; 226 to return the drive member 126; 226 to a stable position of the two positions of the drive member (see...). Figure 10 and 15 ).

[0102] Additionally, each mechanism 100; 200 includes retaining elements 160; 260 for holding the compressible elements 150; 250 in the inactive configuration.

[0103] Therefore, in the active configuration, the compressible elements 150 and 250 do not engage with the retaining elements 160 and 260, and can move along the support surface and the drive members 126 and 226 (see...) Figure 10 and 15 Displacement axes T1 and T2 extending between (see) Figure 2 and 13 Movement. In the inactive configuration, the compressible elements 150; 250 cooperate with the retaining elements 160; 260 to block the displacement (see...). Figure 9 and 16 Here, the displacement axes T1 and T2 coincide with the longitudinal axis of the receiving tube 115 and 215 that houses the compressible elements 150 and 250, and extend along the longitudinal axes of the caps 154 and 254 and the springs 152 and 252.

[0104] During the displacement of the compressible elements 150 and 250, the caps 154 and 254 translate along the displacement axes T1 and T2.

[0105] It is worth noting that retaining elements 160 and 260 are fixed to bases 110 and 210. They cannot move on bases 110 and 210: no part of the retaining element is adapted to displacement relative to the rest of bases 110 and 210.

[0106] Preferably, the retaining elements 160 and 260 are formed together with the bases 110 and 210.

[0107] The retaining element 160; 260 is, for example, a non-deformable rigid element of the base 110; 210. It is integrated into the base 110; 210 in a manner that does not increase the size of the base 110; 210.

[0108] More specifically, retaining elements 160; 260 include retaining surfaces 160A; 260A of the walls of base 110; 210, and compressible elements 150; 250 include complementary latching (hooking) surfaces 150A; 250A adapted to abut against retaining surfaces 160A; 260A of the walls of base 110; 210 to lock compressible elements 150; 250 in the inactive configuration (see...). Figures 2 to 10 13, 15 and 16).

[0109] exist Figures 1 to 11 and Figures 12 to 16In the first and second embodiments shown, the retaining element 160; 260 includes at least one window disposed in the base 110; 210. More specifically, the window is disposed in the cylindrical wall of the receiving cylinder 115; 215 that defines the compressible element 150; 250. The window is partially defined by the retaining surface 160A; 260A. It is located on the bottom side of the receiving cylinder 115; 215, that is, at the rear of the receiving cylinder (see...). Figures 2 to 10 13, 15 and 16).

[0110] exist Figures 1 to 11 In the first embodiment shown, the cap 154 ​​of the compressible element 150 has complex rotational translational motions for transitioning from an active configuration to an inactive configuration or vice versa.

[0111] Complementary locking surfaces 150A of the compressible element 150 are located, for example, on two pins 151 that extend radially from the outer surface of the cylindrical sidewall of the body 154A forming the cap 154. Each pin 151 extends near the free end of the cylindrical sidewall opposite to the head 155 (see...). Figures 2 to 10 (13, 15, and 16). Each pin 151 is fixed, rigid, and non-deformable. Here, two radially opposing pins 151 are provided. These two pins 151 are symmetrical with respect to the longitudinal axis of the cap 154. A portion of the complementary locking surface 150A is located on each pin 151.

[0112] The retaining element 160 also includes two windows that are opposite and symmetrical to the displacement axis T1 of the compressible element 150. Each pin 151 engages with one of the two windows. Each window includes a portion of the retaining surface 160A.

[0113] The cylindrical wall defining the receiving tube 115 also includes longitudinal slits F corresponding to each pin 151 of the cap 154, leading to the window. Each slit F extends parallel to the displacement axis T1 of the compressible element 150. During translational movement of the cap 154, it accommodates the corresponding pin 151 of the cap 154 ​​to transition from an active configuration to a non-active configuration or vice versa.

[0114] Therefore, in the inactive configuration, each pin 151 of the compressible element 150 engages with the edge of the window including the retaining surface 160A to limit the forward translation of the cap 154. The spring 152 is kept compressed between the receiving tube 115 and the head 155 of the cap 154.

[0115] The complementary locking surface 150A of the pin 151 and the retaining surface 160A of the retaining element 160 each include at least one portion extending in a plane perpendicular to the displacement axis T1. Therefore, under the action of the spring 152, the complementary locking surface 150A of the pin 151 abuts against the retaining surface 160A of the window forming the retaining element 160.

[0116] The compressible element 150 is held at the rear of the drive member 126, located in the receiving tube 115, by the engagement between the complementary locking surface 150A and the retaining surface 160A of the pin 151 (see...). Figure 9 ).

[0117] In the inactive configuration, the body 154A of the cap 154 ​​is housed within the receiving tube 115. Only the head 155 of the cap 154 ​​is positioned above the receiving tube 115. Each pin 151 is housed within a corresponding window of the retaining element 160. Regardless of the position of the drive member 126, the head 155 of the cap 154 ​​is a certain distance from the rear surface of the front wall 128 of the drive member 126. Therefore, the compressible element 150 does not engage with the drive member 126.

[0118] Here, the cylindrical wall of the receiving cylinder 115 also includes a rib 167, which extends protrudingly from the retaining surface 160A within the window forming the retaining element 160 (see...). Figure 1 , 5 and 8).

[0119] Each pin 151 includes a complementary groove 157 extending from the complementary latching surface and adapted to receive the rib 167 (see...). Figure 1 , 5 and 8).

[0120] Here, rib 167 is close to slit F and is located in the front part of the window that maintains the outline between the surface and slit F.

[0121] The rib 167 and the complementary groove 157 together form a lateral sealing device for the compressible element 150. In fact, when the compressible element 150 is in an inactive configuration (see...), Figure 4 The engagement between rib 167 and complementary groove 157 prevents any rotational movement of cap 154 ​​within receiver tube 115.

[0122] In the variant, it is clear that the ribs can be supported by pins, and the grooves can be supported by the cylindrical walls of the receiving cylinder.

[0123] The window is large enough along the displacement axis T1 to allow the pin 151 to retract rearward into the window, thereby disengaging the rib 167 from the groove 157. Additionally, the width of the slit F allows the pin 151 to pass through (see...). Figure 5 ).

[0124] The rotational movement of the cap 154 ​​can bring each pin 151 into the axis of the corresponding slit F (see...). Figure 6 The pin 151 can thus slide freely in the slit F. The spring 152 is relaxed, and the head 155 of the cap 154 ​​is pressed against the rear surface of the front wall 128 of the drive member 126 (see...). Figure 7 ).

[0125] The slit F guides the translational movement of the cap 154 ​​of the compressible element 150 along the displacement axis T1. The compressible element 150 is thus in its active configuration (see...). Figure 10 ).

[0126] Preferably, the front wall 128 of the drive member 126 is located at the front of the compressible element 150, that is, above the compressible element 150 when the compressible element 150 is placed on the horizontal support, and the front wall 128 includes a through opening 170 through which the compressible element 150 can be accessed from the front side of the mechanism 100 for the electrical switch (see...). Figure 3 ).

[0127] like Figure 3 As shown, the head 155 of the cap 154 ​​is equipped with a slit 155A for receiving the end of a tool—such as a screwdriver—for rotational control. The through opening 170 of the front wall 128 of the drive member 126 has a shape adapted to restrict the end of the tool to rotate at a predetermined angle.

[0128] Preferably, the through opening 170 (see...) Figure 3 The shape of the compressible element 150 is adapted to guide the screwdriver to rotate at a 45° angle. The transition of the compressible element 150 from one configuration to another is thus achieved by rotating a quarter turn.

[0129] Here, we describe one embodiment in which two radially opposing pins are provided. These two pins ensure satisfactory rigidity of the cap 154 ​​and prevent the cap 154 ​​from being clamped in the receiving tube 115 when the spring 152 is compressed.

[0130] In a variant, a similar embodiment can be envisioned, in which the cap consists of only a single pin.

[0131] exist Figures 12 to 16 In the second embodiment shown, the complementary locking surface 250A of the compressible element 250 belongs to a locking tooth 251 that extends outward from a clamping claw 256 cut from the cylindrical sidewall of the body 250A forming the cap 254 (see...). Figure 13 ).

[0132] The locking tooth 251 is located at the rear of the cap 254. A corresponding window defining the cylindrical wall of the receiver 215 is located near the bottom of the receiver 215 (see...). Figure 12 ).

[0133] Therefore, in the inactive configuration, the front surface of the latching teeth 251 of the cap 254 of the compressible element 250 forming the complementary latching surface 250A engages with the side of the window to limit the forward translation of the cap 254. The spring 252 is compressed between the bottom of the receiving tube 215 and the head 255 of the cap 254.

[0134] The complementary locking surface 250A and the retaining surface 260A of the locking tooth 251 extend in a plane perpendicular to the displacement axis T2. Therefore, under the action of the spring 252, the complementary locking surface 250A of the locking tooth 251 is in close contact with the retaining surface 260A of the window forming the retaining element 260.

[0135] The compressible element 250 is held at the rear of the drive member 226 and located in the receiving tube 215 by the engagement between the complementary locking surface 250A of the locking teeth 251 and the retaining surface 260A (see...). Figure 16 The compressible element 250 is clamped onto the window forming the retaining element 260.

[0136] The head 255 of the cap 254 therefore does not engage with the drive element 226 (see...). Figure 16 ).

[0137] With the aid of the tip of a tool—such as a screwdriver—the clamping claw 256 can be pressed through a window in the cylindrical wall of the receiver 215 that forms the retaining element 260. In this way, the clamping claw 256 bends toward the inside of the cap 254 to release the locking teeth 251 from their engagement with the window provided in the cylindrical wall of the receiver 215.

[0138] Spring 252 is thus relaxed and pushes cap 254 toward drive member 226. Head 255 of cap 254 abuts against the rear surface of front wall 228 of drive member 226, returning drive member 226 to its only possible position of two possible positions. Compressible element 250 is thus in its active configuration (see...) Figure 15 ).

[0139] In a variation, the retaining element may include a recessed portion of a cylindrical wall partially defined by the retaining surface.

[0140] In practice, when using the mechanism 100; 200 according to the invention, the user can easily and quickly transition the compressible element from its active configuration to its inactive configuration or vice versa, such transition allowing from reciprocating flip operation to push-button operation or vice versa.

[0141] When the compressible element 150; 250 is in its inactive position, it is compressed such that the body 154A; 254A of its cap 154; 254 is housed in the receiving tube 115; 215. The head 155; 255 of the cap 154; 254 is kept at a distance from the drive member 126; 226. The drive member 126; 226 is freely positioned in one of its two positions. The electrical switch equipped with mechanism 100; 200 thus performs a reciprocating operation. In the inactive configuration of the compressible element, the two positions of the drive member 126; 226 are stable positions.

[0142] When the compressible element 150; 250 is released from its engagement with the retaining element 160; 260, the spring 152; 252 can extend until the head 155; 255 of the cap 154; 254 contacts the rear surface of the front wall of the drive element 126; 226.

[0143] In the active configuration, it continuously returns the actuators 126 and 226 to one of their two positions. When the user applies sufficient force to the control panel to compress the springs 152 and 252 and flip the actuators 126 and 226, the actuators 126 and 226 can only be temporarily in the other positions. The electrical switch equipped with mechanism 100 and 200 is thus operated as a button.

[0144] In the active configuration of compressible elements 150 and 250, only the position returned by drive elements 126 and 226 is a stable position.

[0145] The compressible element 150; 250—more specifically, spring 152; 252—is characterized by the fact that the compressible element 150; 250 (here, head 155; 255) applies sufficient force to the drive 126; 226 via the cap 154; 254 to hold it in one of its two positions unless the user applies a force to the drive 126; 226 that is opposite to the force generated by the compressible element 150; 250.

[0146] Here, springs 152 and 252 are, for example, helical springs, having an inner diameter of 2.1 mm, an outer diameter of 3 mm, and a height of 13 mm. They are obtained, for example, from a metal wire with a diameter of 0.45 mm, and have a total of 13 turns.

[0147] In the case of the first embodiment, refer to Figures 4 to 7To transition the electrical switch equipped with mechanism 100 from reciprocating toggle operation to push-button operation, the user should perform the following steps. Figures 4 to 7 The left side of the mechanism visually illustrates these steps. Here, the right side of the mechanism in these figures still maintains its reciprocating flipping operation.

[0148] like Figure 4 As shown, the compressible element 150 is initially in an inactive configuration. Both mechanisms 100 shown are in this inactive configuration.

[0149] When the control contact plate of the corresponding electrical switch is actuated, the contact plate will transmit a flipping motion to the drive member 126. As described above, this flipping motion drives the brush 124 of the corresponding mechanism 100 to move between a first contact position and a second contact position. In the first contact position, the movable contact point contacts the fixed contact point of one of the fixed electrical connection terminals, and in the second contact position, the movable contact point contacts the fixed contact point of the other fixed electrical connection terminal.

[0150] To transition to button operation, the user inserts the tip of a screwdriver 1 into the through opening 170 in the front wall 128 of the drive member, and then into the slit 155A of the head 155 of the cap 154. Using the screwdriver tip, the user delves deeper into the compressible element toward the bottom of the receiving cylinder 115. The cap of the compressible element 150 translates from front to rear until the free edge of the cap 154 ​​reaches the bottom of the receiving cylinder 115 (see...). Figure 5 ).

[0151] Then, the user uses a screwdriver (see...) Figure 6 Tightening or loosening is performed through the through opening 170, thereby causing the cap 154 ​​to pivot.

[0152] When the user releases the pressure applied to the screwdriver to keep the spring 152 of the compressible element 150 compressed, each pin 151 of the compressible element 150 slides into its corresponding slit F. The cap 154 ​​is pushed toward the drive member 126. The head 155 contacts the drive member 126. As long as the compressible element is in the active configuration, the action of the compressible element 150 on the drive member 126 continues to push the drive member 126 toward one of its two positions.

[0153] Therefore, when the control touchpad is actuated, the drive member 126 flips to another position only for the time the user applies force to the control touchpad. The movable contact point also flips toward the corresponding fixed contact point in the other position for the time the user applies force to the control touchpad. Then, the spring 152 of the compressible element 150 pushes the drive member back toward the return position (see...). Figure 7 ).

[0154] To resume reciprocating operation, the user inserts the tip of screwdriver 1 through the through opening 170 in the front wall 128 of the drive member into the slit 155A of the head 155 of the cap 154. Using the tip of the screwdriver, the user delves deeper into the compressible element toward the bottom of the receiving cylinder 115. The cap of the compressible element 150 translates from front to rear until the free edge of the cap 154 ​​reaches the bottom of the receiving cylinder 115 (see...). Figure 5 Pin 151 slides into slit F.

[0155] Then, the user uses a screwdriver (see...) Figure 6 The cap 154 ​​is pivoted by loosening or tightening the cap through the through opening 170.

[0156] When the user releases the pressure applied to the screwdriver to keep the spring 152 of the compressible element 150 in a compressed state, each pin 151 of the compressible element 150 slides into its corresponding window, and the complementary locking surface of the pin abuts against the retaining surface 160 of the base. The compressible element 150 remains compressed in its inactive configuration.

[0157] In the second embodiment, in order to transition the electrical switch from reciprocating operation to push-button operation, the user performs the following steps.

[0158] The user presses the clamping claw 256 of the cap 254 through the window of the retaining element 260 of the cylindrical wall of the receiving tube 215 that forms the defining base 210 by passing the tip of a tool—such as a screwdriver.

[0159] The clamping jaw 256 bends and releases the compressible element from its engagement with the retaining element of the base.

[0160] Spring 252 relaxes, and cap 254 is pushed toward drive member 226. Head 255 contacts drive member 226. As described with reference to the first embodiment, as long as the compressible element is in the active configuration, the action of compressible element 250 on drive member 226 continuously pushes drive member 226 toward one of its two positions.

[0161] To resume reciprocating operation, the user inserts the tip of screwdriver 1 through the through opening 270 provided in the front wall 228 of the drive unit (see...). Figure 15 and 16Insert and press the head 255 of the compressible element to penetrate deeper toward the bottom of the receiving cylinder 215. The cap 254 of the compressible element 250 translates from front to rear until the free edge of the cap 254 reaches the bottom of the receiving cylinder 215. Clamping claws 256 engage the retaining surface of the window provided in the cylindrical wall of the receiving cylinder 215 for this purpose. The complementary locking surfaces of the latching teeth 251 abut against the retaining surface of the base. The compressible element 250 remains compressed in its inactive configuration.

[0162] This invention provides an electrical switch that can effortlessly transition from flip-top operation to push-button operation without additional components, and certain parts of the electrical switch are not detachable (separation could lead to the risk of loss), and the electrical switch has a very compact structure.

[0163] This invention is not limited to the embodiments illustrated and shown in the various drawings, and those skilled in the art will understand how to make any modifications according to the spirit of this invention.
