How The Snap in Micro Switches Work

The external mechanical force exerts force on the action reed through the transmission element (press the pin, button, lever, roller, etc.). When the action reed is displaced to the critical point, instant action occurs, which makes the moving contact at the end of the action reed quickly connected or disconnected. After the action reed removes the force on the transmission element, the reaction force will be generated. After the reaction force of the transmission element reaches the action critical point of the reed, the reaction force will be completed instantaneously. The micro switch has small contact spacing, short action stroke, low power and fast on-off speed. The speed of moving contact has nothing to do with the speed of driving element.
