Switch accessories are electromechanical switch devices which are used to make or break the contacts in an electrical circuit. They act as a physical interface between the electrical system and the real world. The primary function of an electrical switch is to change the state of an electrical or mechanical appliance, which is from ON to OFF state or vice versa.
