What is micro switch?
Micro Switch Definition A micro switch has a small contact interval and a snap-action mechanism and uses a specified stroke and a specified force to perform switching operations. It is a switch that covered by a shell and has a drive rod outside. Because of the small contact distance, we not only call it a micro switch but also call it a sensitive switch or snap action switch. The micro switch is composed of 5 major types of constituent elements. The contact distance is small and the torque is large, which is the most obvious characteristic of the switch. Generally, there is a drive rod outside. Micro Switch Working Principle The external mechanical force acts on the leaf spring through the transmission elements, such as press pins, buttons, levers, rollers, etc. When the leaf spring is displaced to the critical point, then the end of the spring leaf and the fixed contact point will turn on or off quickly. And, when the force on the transmission element is removed, the ...
