Problems solved by technology

[0002] The button switch is an important part of the car, especially the seat adjustment button switch is widely used in the car. Some of the existing seat adjustment switches have complex structures, low reliability and high cost; The switch has a simple structure, but the operating force and stroke of the micro switch cannot be adjusted, so the operating stroke and operating force of the entire switch cannot be adjusted, and the button may shake, which affects the user's operating feel and satisfaction

Abstract

The invention provides a switch for improving a return structure. The switch is simple in structure, can realize the adjustment of operation travelling and operating force, and eliminates the phenomenon of button shaking. The switch includes a button, a casing, and a slide member, the slide member is arranged in the casing, the upper part of the slide member penetrates through the avoidance hole corresponding to the casing and then is inserted into the lower installing cavity of the button, the avoidance hole of the casing guarantees that the slide member is possible to move in at least one direction, a corresponding microswitch is arranged in the casing corresponding to the possible moving direction of the slide member, the microswitch is connected with a corresponding circuit board, the lower end face, corresponding to the sliding direction of the slide member, of the upper plate of the casing is provided with a downward protruding baffle block, the position, corresponding to the baffle block, of the slide member is fixedly connected with a spring, the external free end of the spring stretches freely under an off-work state, and under the work state, the external free end of the spring applies force and acts on the corresponding baffle block.

Description

technical field [0001] The invention relates to the technical field of an automobile button switch, in particular to a switch with an improved return structure. Background technique [0002] The button switch is an important part of the car, especially the seat adjustment button switch is widely used in the car. Some of the existing seat adjustment switches have complex structures, low reliability and high cost; The switch has a simple structure, but the operating force and stroke of the micro switch cannot be adjusted, so the operating stroke and operating force of the entire switch cannot be adjusted, and the button may shake, which affects the user's operating feel and satisfaction. Contents of the invention [0003] In view of the above problems, the present invention provides a switch with an improved return structure, which has a simple structure, can adjust the operating stroke and operating force, and eliminate the phenomenon of button shaking. [0004] A switch w...
