Frequently Asked Question
Do you have any question?
When an external mechanical force acts on the spring movement through the transmission element (according to a pin, a button, a lever and a roller), when the spring moves to a critical point to produce an instantaneous action, it moves quickly on or off at the end of the moving contact and the fixed contact. When the force transfer element is disassembled, the spring movement produces a reverse force, and when the transmission element is reversed, it is twisted into the critical working point of the spring, and the instantaneous complete reverse action is completely reversed. The micro switch contacts have small spacing, short movement, small press power, and fast break. The speed at which the contact is moved is independent of the speed of the actuator.
Micro switch is a kind of pressure actuation of the fast transfer switch, because the contact spacing of its switch is relatively small, so the name of the micro switch, also known as the sensitive switch. The electrical text symbol is: SM.
