[0025] The switch structure in this embodiment is as follows: Figures 1 to 5As shown, it includes a mounting seat and a switch unit; the switch unit includes a circuit board 1 fixed on the mounting seat, a key switch 2 mounted on the circuit board 1 and a touch-pressure assembly 3 for controlling the key switch 2; the key switch 2 includes a first switch 21, a second switch 22 and a third switch 23; the touch-pressure assembly 3 includes a swing block 31 swingably arranged on the mounting seat and a pressure handle 32 movable up and down on the swing block 31, the swing block 31 is provided with a first touch-pressure portion 311 and a second touch-pressure portion 312 on both sides of its swing axis, the first touch-pressure portion 311 and the second touch-pressure portion 312 are respectively located above the first switch 21 and the second switch 22, and the bottom of the pressure handle 32 is provided with a third touch-pressure portion 321 located above the third switch 23. The key switch 2 in this embodiment can be set as a touch switch or a micro switch.

[0026] With the structure of this embodiment, in actual operation, pressing the handle 32 downward can press the button of the third switch 23 through the third pressing portion 321, and the swing block 31 is driven to swing by applying lateral thrust to the handle 32, and then the first pressing portion 311 or the second pressing portion 312 moves downward and presses the button of the first switch 21 or the second switch 22, so that the three switches can be controlled by one handle 32, and the structure is simple and the installation space is small. After the pressure applied to the handle 32 is removed, the swing block 31 and the handle 32 are reset by the reset elastic force provided by the key switch 2.

[0027] In this embodiment, a mounting hole 310 which passes through from top to bottom is provided in the middle of the pendulum block 31, and the lower end of the pressing handle 32 extends into the mounting hole 310. The pressing handle 32 can move up and down in the mounting hole 310, and drive the pendulum block 31 to swing when the pressing handle 32 swings. In order to limit the pressing handle 32 to be installed on the pendulum block 31, an anti-detachment hook 322 is further provided on the pressing handle 32, and the anti-detachment hook 322 cooperates with the pendulum block 31 to prevent the pressing handle 32 from detaching from the pendulum block 31.

[0028] Specifically, an anti-detachment hook 322 is disposed on each side of the third pressing portion 321 of the pressing handle 32 , and the anti-detachment hook 322 cooperates with a step stopper at the mounting hole 310 .

[0029] In some embodiments, the mounting base adopts a split assembly structure, specifically including a base 4 and a shell cover 5 covering the base 4; a first through hole 50 is set on the shell cover 5 at a position corresponding to the touch-pressure assembly 3, and the first through hole 50 is set for the upper end of the pressure handle 32 to extend out of the shell cover 5. A concave cavity 41 opening upward is provided on the upper part of the base 4, and the circuit board 1 is fixed in the concave cavity 41 and covered by a sealant layer (not shown in the figure). The circuit board 1 is coated by filling the sealant in the concave cavity 41, thereby enhancing the waterproof performance.

[0030] Exemplarily, the shell cover 5 can be snap-fitted to the base 4 by means of a buckle; or, the shell cover 5 is fixedly connected to the base 4 by means of screws.

[0031] In some embodiments, Figure 4 and Figure 5 As shown, pivot shafts 313 are provided on both sides of the middle part of the pendulum block 31, and a limiting shaft groove 42 is provided on the base 4. During assembly, the pivot shaft 313 is placed in the limiting shaft groove 42 through the groove. After the shell cover 5 and the base 4 are combined, the corresponding part of the shell cover 5 is abutted against the groove, so that the pivot shaft 313 is abutted and limited in the limiting shaft groove 42, and the pendulum block 31 is easy to install.

[0032] In some embodiments, a lamp bead 11 and a light-transmitting cover 12 covering the lamp bead 11 are connected to the circuit board 1, and a second perforation 51 is provided on the shell cover 5 at a position corresponding to the light-transmitting cover 12. The light emitted by the lamp bead 11 can be transmitted through the light-transmitting cover 12 to have a light indication effect; the light-transmitting cover 12 can be connected to the circuit board 1 by a snap-on manner; during production, it is necessary to ensure that the lamp bead 11 cannot be covered by the sealant layer covering the circuit board 1, so as to ensure that the light emitted by the lamp bead 11 can be effectively transmitted outward.

[0033] In order to enhance the protection performance of the key switch and improve the waterproof capability, a sealing rubber sleeve 6 is sleeved outside the first switch 21 , the second switch 22 and the third switch 23 .

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
