The external mechanical force is applied to the action reed through the transmission element (press pin, button, lever, roller, etc.). When the action reed is moved to the critical point, instantaneous action is generated, so that the moving contact at the end of the action reed is quickly connected or disconnected with the fixed contact.

When the force on the transmission element is removed, the action reed produces reverse action force, and when the reverse travel of the transmission element reaches the critical point of the action of the reed, the reverse action is instantaneous.The micro-switch has the advantages of small contact spacing, short action stroke, small press power and quick on-off.The speed of the moving contact has nothing to do with the speed of the transmission element
