[0002] With the rapid development of modern information technology, switches, as electronic components for controlling signal transmission, are widely used in circuit switching of various electronic devices, and their main function is to turn on or off certain circuits. There are various types of switches, which can be classified by structure, including micro switches, rocker switches, toggle switches, knob switches, key switches, button switches, and membrane switches. Among them, micro switches are a kind of electronic components with the characteristics of sensitive switching, small size, small contact spacing, and high control precision. Their function is to control the on-off of the circuit or realize the switching of the circuit.

[0003] Micro switch is a kind of contact mechanism and a kind of quick action mechanism, which uses a specified stroke and force to complete the switching action of the switch. For micro switch, because its contact spacing is very small, it is called micro switch, or also called sensitive switch. Micro switch usually has an outer shell, and a plurality of conductive parts are arranged in the shell. One of the conductive parts is connected with an elastic part and provided with a moving contact. The conductive part is elastically abutted against the button on the micro switch under the action of the elastic part. When the button is pressed to overcome the pre-tightening force of the elastic part, the conductive part is displaced to the moving contact to contact the static contact of the other conductive part to realize conduction.
