The Origin and Development of Micro Switch

Micro switch is a pressure-actuated fast switch, also known as sensitive switch. Its working principle is that the external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.), and accumulates the energy to the critical point to produce an instantaneous action. The micro switch makes the action reed The moving contact at the end is quickly connected or disconnected with the fixed contact. 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 reed, the reverse action is completed instantaneously. The contact spacing of the micro switch is small, the action stroke is short, the pressing power is small, and
