It is a switch in which the external mechanical force acts on the action reed through the transmission element, so that the fixed contact at the end and the movable contact are quickly connected or disconnected.

Micro switches has a small contact interval and a quick-action mechanism. The contact mechanism that performs the switching action with a specified stroke and force is covered by a casing, with an external actuator and a small shape.
Micro switches are composed of five major categories of components. The contact distance is small and the torque is large. Usually there is a drive rod on the outside.

How the micro switch works

The external mechanical force acts on the action reed through transmission elements (pressing pins, buttons, levers, rollers, etc.), and when the action reed is displaced to the critical point, an instantaneous action occurs, making the moving contact at the end of the action reed and the fixed contact point to switch on or off quickly.
When the force on the transmission element is removed, the action reed generates a reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously.

The contact distance of the micro switch is small, the action stroke is short, the pressing power is small, and the on-off is fast. The action speed of the moving contact has nothing to do with the action speed of the transmission element.

There are many types of micro switches, and there are hundreds of internal structures. According to the volume, there are ordinary, small, and ultra-small; according to the protection performance, there are waterproof, dust-proof, and explosion-proof types; Single type, double type, multi-link type.

There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also make the switch disconnect); according to the breaking capacity, there are ordinary type, DC type, micro-current type, and high-current type.
