Terminal switches are mechanical devices primarily used to limit the movement of various mechanisms that perform primarily reciprocal motion. Constructively encompass a lever system mechanically coupled to one or more electrical contacts. They find a wide application in automatic machine tool control, motion control, manipulation or action control, signalling, blocking of control and operating circuits.
