How the Micro Switch works

The micro switch is a fast switch that is pressed and actuated, also called a sensitive switch.

The working principle is that the external mechanical force acts on the action reed through the transmission component (by pin, button, lever, roller, etc.), and after the energy is accumulated to the critical point, an instantaneous action is generated to make the end of the action reed move. The contact and the fixed contact are quickly turned on or off. When the force on the transmission component is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is instantaneously completed.

The micro switch has a small contact pitch, a short stroke, a small power, and a fast switching. The speed of the moving contact is independent of the speed of the transmission element.

The micro switch is based on the pin type, and can be derived from the button short stroke type, button large stroke type, button extra large stroke type, roller button type, reed roller type, lever roller type, short boom type, long boom type. and many more.

The micro switch is used in electronic devices and other devices for devices such as automatic control and safety protection of frequently changing circuits.

The micro switch is divided into large, medium and small. It can be waterproof (used in liquid environment) and common type according to different needs.

The switch connects two lines to provide on/off control for electrical appliances and machines. Widely used in mouse, household appliances, industrial machinery, motorcycles, etc., the switch is small, but plays an irreplaceable role.

Some are also called contact switches!
