Microswitch is a contact mechanism with a small contact spacing and quick-acting mechanism, with a predetermined stroke and the provisions of the force to switch the action, covered with a shell, the external drive rod with a switch, because the contact spacing switch Relatively small, hence the name micro switch, also known as sensitive switch. Electrical text symbol: SM.
External mechanical force through the transmission element (by the pin, button, lever, roller, etc.) force acting on the reed, when the reed moves to the critical point when the instantaneous action, the action reed at the end of the moving contact and touch Point quickly connected or disconnected.
When the force on the transmission element is removed, the action reed produces reverse action force, when the transmission element reverse stroke reaches the critical point of reed action, the instantaneous reverse action. Microswitch contact spacing is small, short stroke, press a small power, on-off quickly. The moving speed of its moving contact has nothing to do with the moving speed of the transmission element.
Micro-switch, as the name suggests, the use of very small intensity switch. The smaller the electric shock distance, a larger torque. General external drive rod. In the size of a small, super small, super small and so on. Function is waterproof. The most common application is the mouse button.
