Abstract
The disclosure depicts a novel pushbutton switch mechanism having a pair of pushbutton switches with electrical contacts and an interlock mechanism between the switches. The interlock mechanism comprises; a shoulder on each of the pushbutton switches, an interlock plunger for contacting the shoulders of the pushbutton switches, and a return spring in contact with the interlock plunger for retaining the plunger in a predetermined position. A plunger support and a plunger guide in the pushbutton switch mechanism for defining an area in which the interlock plunger is contained. When one of the pushbutton switches is depressed, the interlock plunger contacts the shoulder of the other pushbutton switch thereby preventing the other pushbutton switch from being depressed simultaneously.
