Types and Applications of Unionwell Micro Switches

The micro switch is composed of 5 major components. Its contacts have small spacing and large torque. Usually, there is a actuating lever.

Internal structure of micro switches: pin plunger, rods, housing, common terminals, NO terminals, contacts, cutting needles, shrapnel, moving pieces, rubber covers.
