Abstract
A limit switch comprises a snap action switch component and an actuator, said actuator being constructed so as to selectively actuate the snap action switch component with respect to the rotating direction of a rotating shaft of the actuator. A rotational motion of the rotating shaft is transmitted to the snap action switch component through a pair of levers and a driving plunger member. The pair of levers are pivotally secured under the rotating shaft and the driving plunger member is rotatably and reciprocatingly secured under said pair of levers. Free ends of the levers are selectively engageable with the top surface of the driving plunger member, an upper portion of which is partially cut out. By setting the driving plunger member in a predetermined rotating angular position, one of said free lever ends is disengaged from said driving plunger member.
