Abstract
A snap action type of electric switch in which a contact plate is provided with a movable contact facing a stationary contact located in a housing. The movable contact is free to move back and forth, and the contact plate is connected through an intermediate snap spring to a switching rod which extends at the back of the spring and is also free to move back and forth. The contact plate has a play space in forward and rearward directions in relation to the snap spring, and is urged in forward direction by an auxiliary spring. The snap spring is formed of an elastic metal strip which is bent into a channel form. A pair of levers bridge a neck portion of an enlarged head portion of the switching rod. When moving back and forth, the rod 5 may apply a predetermined movement to the snap spring. A holding member extends rearwards from the contact plate and has an opening into which a transverse portion of the snap spring is loosely inserted so as to form the play space.
