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 switch action. It is covered by a shell; a switch with a drive rod outside, because the contact spacing of the switch is relatively small Small, hence the name of the micro switch, also called the sensitive switch, the electrical text symbol is: SM.
The main function of the micro switch is that 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 switch is small, the action stroke is short, the pressing force is small, the on-off is rapid, and the action speed of its movable contact has nothing to do with the action speed of the transmission element.
