The screws used can be M2 screws.

[0075] Place the insulating member 20 in the lower housing 11, place the base 13 on the insulating member 20, and insert the screws from the bottom. The screws pass through the lower housing 11 and the insulating member 20 in sequence and are locked and fixed on the base 13; install the moving assembly 40, install the screw fixing limit seat 425 on the lower housing 11, install the elastic member 424, the push rod 421, the fixing member 422 and the pulling member 423, and install the contact bridge 41; finally, cover and fix the upper cover 12 on the lower housing 11.

[0076] In the initial state, the two moving contacts on one side of the contact bridge 41 are in contact with the two second static contacts 312 respectively; when the travel switch is triggered by an external force, the external force acts on the roller 426 and pushes the push rod 421 to move along the first direction, the elastic member 424 is gradually compressed, the fixing member 422 moves with the push rod 421, the pulling member 423 pulls the contact bridge 41, and the contact bridge 41 gradually approaches the first static contacts 311 until the two moving contacts on the other side of the contact bridge 41 are in contact with the two first static contacts 311 respectively; when the external force is lost, the push rod 421 is gradually reset under the action of the elastic member 424, thereby driving the fixing member 422, the pulling member 423 and the contact bridge 41 to reset.

[0077] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
