How micro switches work
Time:2019-07-19
Micro switch is a pressure actuated fast switch, also known as sensitive switch.
Its working principle is: the external mechanical force through the transmission element (press pin, button, lever, roller, etc.) will be used on the action reed, and the energy accumulation to the critical point, generate instantaneous action, make the action reed end of the moving contact and fixed contact quickly connected or disconnected.When the acting force on the transmission element is removed, the action reed generates a reverse action force. When the reverse travel of the transmission element reaches the action critical point of the reed, the reverse action is immediately completed.Micro switch contact distance is small, short action travel, press power small, quick on and off.The speed of the moving contact is independent of the speed of the driving element.


Micro switch push pin type as the basic type, can be derived from button short stroke type, button big stroke type, button big stroke type, roller button button type, reed roller type, lever roller type, short arm type, long arm type and so on.Micro switches are used in electronic devices and other devices for automatic control and safety protection that require frequent circuit switching.Micro switch is divided into large, medium, small, according to the needs of different points can have waterproof model (in liquid environments) and ordinary, and switch to connect two lines, provide general power control for electrical appliances, machinery, widely used in the mouse, household appliances, industrial machinery, motorcycles and other places, switch are small, but plays an irreplaceable role.
Some also call contact switch!
