Abstract
An actuating member in an electric switch housing is provided with a bore that opens downwardly inside the housing and contains a plunger slidably mounted therein and projecting from the lower end of the bore. A coil spring in the bore presses the plunger down against a movable contact to press it against stationary contacts. The plunger and movable contact are interconnected for movement of the contact by the actuating member, and the actuating member and plunger are provided with interengaging means for limiting downward movement of the plunger in the bore in the absence of the movable contact, whereby the plunger cannot escape from the actuating member.
