Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a panel switch with a flush operating surface. Background Technology

[0002] Switches are one of the most basic and widely used components in electrical control systems, used to control the on / off state of circuits. Among them, panel switches are widely used in household appliances, lighting systems, industrial equipment, and building electrical installations due to their advantages such as ease of operation, clear tactile feedback, and reliable structure.

[0003] With the increasing demands for aesthetics, overall design, and human-computer interaction in modern architecture and interior design, the appearance design of panel switches is receiving more and more attention. Especially in multi-gang switch applications, users not only focus on the switch's operational performance and safety but also increasingly value its visual harmony and aesthetics. Traditional multi-gang panel switches typically consist of multiple independent rocker buttons, each controlling a separate circuit. In practical use, when some switches are on while others are off, due to the rocker button's operating principle, the operating surfaces often appear uneven—one end of a button is raised while the other is lowered—creating a height difference between adjacent buttons and affecting the overall visual appeal of the panel.

[0004] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a panel switch structure that can keep the operating surfaces of each rocker button flush in all working states and has a clear and reliable status indication function.

[0006] This utility model is achieved through the following technical solution:

[0007] A panel switch with a flush operating surface includes a mounting base. The mounting base has at least two switch modules and rocker buttons rotatably connected to it, each corresponding to and controlling the on / off state of a switch module. The exposed portion of each rocker button has an operating surface. A reset mechanism is provided between the mounting base and the rocker buttons to ensure that the operating surfaces of each rocker button remain flush when the switch modules are closed or open. A swing arm is provided between the mounting base and the rocker buttons. The swing arm has a first indicator for indicating that the switch modules are closed and a second indicator for indicating that the switch modules are open. A switching mechanism is also provided between the mounting base and the rocker buttons to drive the swing arm to swing when the rocker buttons are pressed. The operating surface has an observation window for observing the first or second indicator after the swing arm swings.

[0008] As described above, a panel switch with a flush operating surface includes a switch module comprising a first terminal and a second terminal on a mounting base. The second terminal is conductively connected to a first stationary contact, and the first terminal is conductively connected to a movable contact. A swinging member is movably connected to the mounting base, and a driving member is slidably connected to the mounting base. A transmission structure is provided between the swinging member and the driving member to convert the sliding of the driving member into the swinging of the swinging member, thereby driving the movable contact to connect and disconnect with the first stationary contact.

[0009] As described above, a panel switch with a flush operating surface is provided between the mounting base and the rocker button to limit the rotation angle of the rocker button. The reset mechanism includes a first reset spring located between the mounting base and the driving member, which can lift the driving member to drive the rocker button to reset after being pressed.

[0010] As described above, a panel switch with a flush operating surface has a first inclined surface on the left side of the swing member that gradually decreases from right to left, and a second inclined surface on the right side that gradually decreases from left to right. The transmission structure includes a slider that is slidably connected to a drive member in the left-right direction. The slider has a third inclined surface that gradually increases from left to right and a fourth inclined surface that gradually increases from right to left. A second return spring is provided between the drive member and the slider, which allows the slider to slide towards the center of the drive member. When the swing member swings to the left, the fourth inclined surface and the second inclined surface are vertically opposite each other. When the swing member swings to the right, the third inclined surface and the first inclined surface are vertically opposite each other.

[0011] As described above, in a panel switch with a flush operating surface, the middle part of the swing arm is rotatably connected to the mounting base, the first indicator and the second indicator are connected to one end of the swing arm, and the switching mechanism includes a first push block located on the left side of the swing arm and a second push block located on the right side of the swing arm, with a slot between the first push block and the second push block for the other end of the swing arm to be inserted.

[0012] As described above, a panel switch with a flush operating surface includes a third terminal block disposed on a mounting base. The third terminal block is electrically connected to a second stationary contact piece, and when the driving member is pressed, it can switch the connection between the moving contact piece and the first stationary contact piece or the second stationary contact piece.

[0013] As described above, a panel switch with a flush operating surface has a telescopic block slidably connected to the swing member, a third spring between the swing member and the telescopic block to push the telescopic block toward the moving contact piece, and an insertion interface fork at the end of the telescopic block and connected to the upper end of the moving contact piece.

[0014] As described above, a panel switch with a flush operating surface includes a mounting base comprising a base, a support frame, a bracket, and a top cover. The base and the support frame are connected by a snap-fit ​​structure, the bracket and the support frame are connected by a snap-fit ​​structure, and the top cover and the bracket are connected by a snap-fit ​​structure.

[0015] As described above, a panel switch with a flush operating surface has guardrails on both sides of the top cover, and the upper surface of the guardrails is flush with the operating surface.

[0016] As described above, a panel switch with a flush operating surface has different color blocks on the first and second indicator marks.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. This product features a reset mechanism between the mounting base and the rocker buttons, ensuring that the operating surfaces of all rocker buttons remain on the same horizontal plane when any switch module is in the closed or open state. This eliminates the unevenness often seen in traditional rocker switches. Even when multiple switches are in different on / off states, the panel maintains a flat and uniform visual effect, greatly enhancing the product's aesthetics and modernity, and meeting the decorative coordination requirements of high-end homes and commercial spaces.

[0019] 2. This product features a swing arm and switching mechanism between the rocker button and the mounting base, and an observation window on the operating surface. When the user presses the rocker button, the switching mechanism pushes the swing arm to swing, causing the corresponding first or second indicator to stop at the position in the observation window, thus clearly and intuitively displaying the current on / off state of the switch module. Users do not need to touch or memorize the position; they can quickly identify the circuit status visually.

[0020] 3. The indication function is achieved through a swing arm and switching mechanism, which is a purely mechanical linkage structure. It does not rely on external power supply or electronic components, thus avoiding indication failure caused by circuit failure, lamp aging or battery depletion, and has higher reliability and longer service life.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1 to 9 The panel switch shown includes a mounting base 1, on which at least two switch modules are mounted and rocker buttons 3 are rotatably connected, each corresponding to and controlling the on / off state of a switch module. The exposed portion of each rocker button 3 has an operating surface 31. A reset mechanism 4 is provided between the mounting base 1 and the rocker buttons 3 so that the operating surfaces 31 of each rocker button 3 remain flush when the switch modules are closed or open. A swing arm 5 is provided between the mounting base 1 and the rocker buttons 3. The swing arm 5 has a first indicator 61 for indicating that the switch modules are closed and a second indicator 62 for indicating that the switch modules are open. A switching mechanism 7 is also provided between the mounting base 1 and the rocker buttons 3, which can push the swing arm 5 to swing when the rocker buttons 3 are pressed. The operating surface 31 has an observation window 8 for observing the first indicator 61 or the second indicator 62 after the swing arm 5 swings.

[0033] This product ensures that the operating surfaces 31 of all rocker buttons 3 remain on the same plane regardless of the switch's on / off state by setting a reset mechanism between the mounting base 1 and the rocker button 3, thus avoiding the "one high, one low" phenomenon of traditional panel switches and improving the overall aesthetics. At the same time, a swing arm 5, a switching mechanism 7, and an observation window 8 on the operating surface 31 are provided between the rocker button 3 and the mounting base 1. The status indication is achieved through pure mechanical linkage: when the rocker button 3 is pressed, the switching mechanism 7 drives the swing arm 5 to move, so that the corresponding indicator appears in the observation window 8, clearly showing the switch's on / off state. It does not rely on power supply or electronic components and has high reliability and long life.

[0034] Specifically, the switch module includes a first terminal 21 and a second terminal 22 disposed on the mounting base 1. The second terminal 22 is conductively connected to a first stationary contact 23, and the first terminal 21 is conductively connected to a moving contact 24. A swing member 201 is movably connected to the mounting base 1, and a driving member 202 is also slidably connected to the mounting base 1. A transmission structure is provided between the swing member 201 and the driving member 202 to convert the sliding of the driving member 202 into the swing of the swing member 201, thereby driving the moving contact 24 to be connected and disconnected from the first stationary contact 23.

[0035] Furthermore, a limiting structure 32 for restricting the rotation angle of the rocker button 3 is provided between the mounting base 1 and the rocker button 3. The limiting structure 32 can be a locking block structure, or other structures that can restrict its rotation. The reset mechanism 4 includes a first reset spring located between the mounting base 1 and the driving member 202, which can lift the driving member 202 to drive the rocker button 3 to reset after being pressed. This keeps all operating surfaces 31 on the same plane.

[0036] Furthermore, the left side of the swing member 201 is provided with a first inclined surface 2011 that gradually decreases from right to left, and the right side of the swing member 201 is provided with a second inclined surface 2012 that gradually decreases from left to right. The transmission structure includes a slider 203 that is slidably connected to the driving member 202 in the left-right direction. The slider 203 is provided with a third inclined surface 2031 that gradually increases from left to right and a fourth inclined surface 2032 that gradually increases from right to left. A second return spring 2033 is provided between the driving member 202 and the slider 203, which allows the slider 203 to slide towards the middle of the driving member 202. When the swing member 201 swings to the left, the fourth inclined surface 2032 and the second inclined surface 2012 are vertically opposite each other. When the swing member 201 swings to the right, the third inclined surface 2031 and the first inclined surface 2011 are vertically opposite each other.

[0037] The oscillating component 201 can only be in one of two states: oscillating to the left or oscillating to the right. If the oscillating component 201 has oscillated to the right, its first inclined surface 2011 is tilted upwards. When the rocker button 3 is pressed, the driving component 202 moves downwards, and the third inclined surface 2031 first contacts and presses against the first inclined surface 2011. Under this pressure, the slider 203 moves to the left. As the driving component 202 continues to move downwards, the slider 203 presses down on the left side of the oscillating component 201, causing it to swing to the left. Since the slider 203 has moved to the left, it will never contact the right side of the oscillating component 201 as the driving component 202 continues to move downwards. When the rocker button 3 is released, the driving component 202 and the rocker button 3 both return to their original positions under the action of the first return spring. Under the action of the second return spring 2033, the slider 203 returns to its original position towards the center of the driving component 202, but the oscillating component 201 remains in its original state. Conversely, if the swing member 201 has already swung to the left, its second inclined surface 2012 will be tilted upwards. When the rocker button 3 is pressed, the slider 203 will press down on the right side of the swing member 201, causing it to swing to the right.

[0038] Furthermore, the switch module also includes a third terminal 25 disposed on the mounting base 1. The third terminal 25 is electrically connected to a second stationary contact 26. When the driving member 202 is pressed, the moving contact 24 can switch its connection with either the first stationary contact 23 or the second stationary contact 26. The connection between the first terminal 21 and the third terminal 25 can be used as a normally closed contact, and the connection between the first terminal 21 and the second terminal 22 can be used as a normally open contact, thereby further increasing the functional versatility of the panel switch.

[0039] In one embodiment, a telescopic block 2113 is slidably connected to the swing member 201. A third spring 2114 is provided between the swing member 201 and the telescopic block 2113 to push the telescopic block 2113 against the movable contact piece 24. The end of the telescopic block 2113 is provided with a forked insertion interface 2115 that forks into the upper end of the movable contact piece 24. The telescopic block 2113 presses against the movable contact piece 24, thereby keeping it in a conductive or disconnected state.

[0040] In one embodiment, the middle part of the swing arm 5 is rotatably connected to the mounting base 1. The first indicator 61 and the second indicator 62 are connected to one end of the swing arm 5. The switching mechanism 7 includes a first push block 71 located on the left side of the swing member 201 and a second push block 72 located on the right side of the swing member 201. A slot 73 is provided between the first push block 71 and the second push block 72 for the other end of the swing arm 5 to be inserted. By pushing one end of the swing arm 5 with the first push block 71 and the second push block 72, the swing arm 5 is rotated, thereby switching the first indicator 61 or the second indicator 62 to the position of the observation window 8 for the user to observe the on / off state of the switch.

[0041] Furthermore, the first indicator 61 and the second indicator 62 have different color blocks. Of course, the first indicator 61 and the second indicator 62 can also be text or patterns.

[0042] In one embodiment, the mounting base 1 includes a bottom shell 11, a support frame 12, a bracket 13, and a top cover 14. It features a modular design to facilitate the processing of each component. The bottom shell is connected to the support frame 12 via a snap-fit ​​structure, the bracket 13 is connected to the support frame 12 via a snap-fit ​​structure, and the top cover 14 is connected to the bracket 13 via a snap-fit ​​structure, thereby facilitating the assembly of each component.

[0043] Furthermore, the upper cover 14 is provided with guardrails 141 on both the left and right sides, which can block the rocker button 3, thereby preventing foreign objects from entering the lower part of the rocker button 3 through the side gap. The upper surface of the guardrail 141 is flush with the operating surface 31, thus making the appearance more aesthetically pleasing.

[0044] All the terminals mentioned above are standard terminals in this field, and will not be described in detail here.
