PUSHBUTTON SWITCH WITH ADJUSTABLE CONTACT PLATES FOR NORMALLY ON, NORMALLY OFF, AND MOMENTARY ACTION

摘要

A contactor is provided having a cylindrical housing containing an axially operable spring biased contacting plunger. A U-shaped contact spring is supported by the plunger and extends longitudinally along the axis of the plunger having laterally disposed contact points near its ends. A contact supporting base is provided having a central opening extending axially within the base for the reception of the contact points. Contact plates are secured to the contact supporting base on opposite sides of the central opening and having contact ribs extending into the central opening for making electrical connection with the contact points. At least one of the contact plates can be selectively secured to the contact supporting base in one position or another for effecting circuit closures at respectively different operating positions of the plunger.
