[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that a sealing gasket is fixedly connected to the bottom of the cover plate 3, which seals the connection between the cover plate 3 and the base 1, preventing water vapor and dust from entering from the connection to contaminate the electronic components inside the touch switch, effectively extending the service life of the device.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the outer wall of the limiting hole 5 fits tightly with the inner wall of the limiting column 6, and the inner wall of the limiting hole 5 is fixedly connected with an anti-slip ring, which plays a guiding role in the detachable connection between the cover plate 3 and the base 1. At the same time, the anti-slip ring increases the friction between the limiting hole 5 and the limiting column 6, further stabilizing the connection between the cover plate 3 and the base 1.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the multiple fixing feet 12 are symmetrically distributed on the outer wall of the driving spring piece 11 with the center of the circle, and the multiple fixing feet 12 are all provided with through holes, which cooperate with the round rods set on the inner wall of the base 1 to fix the driving spring piece 11 and avoid the driving spring piece 11 from detaching when the touch switch vibrates.

[0026] According to the above working process, it can be known that by setting evenly distributed fixing feet 12 on the outer wall of the driving spring piece 11, a circular hole is opened on the surface of the fixing foot 12, which cooperates with the round rod set on the inner wall of the base 1 to fix the driving spring piece 11 and improve the stability of the device.

By setting the clamping mechanism 7, the detachable connection between the cover plate 3 and the base 1 is completed, which is convenient for the disassembly and assembly of the touch switch, and is convenient for its disassembly, maintenance and replacement of parts.

[0028] Further as Figure 4 As shown, it is worth explaining in detail that a limiting groove corresponding to the slide plate 704 is opened inside the base 1, which limits the movement of the slide plate 704 so that it can only move in the horizontal direction, thereby cooperating with the spring 705 to press and reset the lock 703.

[0029] Further as Figure 4As shown, it is worth explaining in detail that a lock hole corresponding to the lock buckle 703 is opened on the outer side of the snap-in plate 8.

Under the action of the spring 705, the lock 703 locks the clamping plate 8 to complete the detachable connection between the cover plate 3 and the base 1. After the installation is completed, when the user presses the button 14, the button 14 presses down the buffer spring sheet 13 to cause it to undergo elastic deformation, thereby driving the driving spring sheet 11 to undergo a concave deformation, so that the first terminal 9 and the second terminal 10 are connected to start working.

[0031] In summary: by setting the clamping mechanism 7, the detachable connection between the cover plate 3 and the base 1 is completed, which is convenient for the disassembly and assembly of the touch switch, and is convenient for its disassembly, maintenance and replacement of parts; by setting evenly distributed fixing feet 12 on the outer wall of the driving spring piece 11, the surface of the fixing feet 12 is provided with round holes, which cooperate with the round rods set on the inner wall of the base 1, so as to fix the driving spring piece 11 and improve the stability of the device.
