Micro Switches And Working Principle

Understanding micro switches and working principle is suitable for selecting proper switches for specific applications. Micro switch working principle: when the external operation force touches on action springs by transfer component ( rolos, levers, or buttons), the action springs will move to the contact point and proceed with a snap action to connect with the external circuit suddenly or close. If the operating force is removed, the action springs produce reverse force, transfer to the contact, and then finish the reverse action of a sudden.

The micro switch is with small contact gap and short travel distance, requiring little operation force to make snap action happen. The micro switch is a kind of electronic component; it is slim and petite but necessary for a household appliance or electronic equipment. A micro switch also called a “miniature snap action switch,” is like a machine with its working principle.

How does a micro switch work internally?

A micro switch comprises a switching casing, a button on the switch casing, a pedestal located in the casing, and the terminals connected to the external circuits. These several parts make a complete micro switch or miniature snap action switch work correctly.
