[0002] A micro switch is a switch with a small contact spacing and a snap-action mechanism. It uses a specified stroke and a specified force to perform a switch action. It is covered with a shell and has a drive rod on the outside. Because the contact spacing of the switch is relatively small, it is called a micro switch, also known as a sensitive switch. It is also called a sensitive switch or a snap-action switch. A quick switch actuated by pressure. It is used for door switches in anti-theft systems, etc.

[0003] However, the existing micro switches need to be frequently touched, and may be offset by other external forces, resulting in failure to accurately touch the switch every time. In addition, due to the use environment of some micro switches, when they are used for a long time, the temperature of the switch inside the power supply will become high due to the high pressure. The long-term high temperature will damage the micro switch, causing the internal transmission components to fail to work properly, and a new micro switch needs to be replaced. Therefore, those skilled in the art provide a micro switch with high flexibility to solve the problems raised in the above background technology. Summary of the invention
