Background
The microswitch is a switch which has a minute contact interval and a quick action mechanism, performs a switching action by a specified stroke and a specified force, is covered by a shell, and has a driving rod outside.
The principle is that external mechanical force acts on an action reed through a transmission element (a press pin, a button, a lever, a roller and the like), and when the action reed moves to a critical point, instantaneous action is generated, so that a movable contact at the tail end of the action reed is quickly connected with or disconnected from a fixed contact. When the acting force on the transmission element is removed, the action reed generates reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is instantly finished. The micro switch has the advantages of small contact distance, short action stroke, small pressing power and quick on-off. The moving speed of the moving contact is independent of the moving speed of the transmission element.
Gaps exist at the joint of the upper cover and the lower cover of the microswitch and around the pressing head, and dust and water enter the microswitch through the gaps to influence the normal work of the switch.
