A micro switch is a contact mechanism that has a small contact interval and a snap-action mechanism, and uses a specified stroke and a specified force to perform switching operations. It is covered by a housing and has a drive rod outside of it.
External mechanical force acts on the action reed through transmission elements (press pins, buttons, levers, rollers, etc.). When the action reed is displaced to the critical point, an instantaneous action is generated, so that the moving contact at the end of the action reed is in contact with the fixed contact. Tap to quickly turn on or off.
When the force on the transmission element is removed, the action reed produces a reverse action force. 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 contact distance of the micro switch is small, the action stroke is short, the pressing force is small, and the on-off is rapid. The movement speed of the moving contact has nothing to do with the movement speed of the transmission element.
