Abstract
A pair of pushbuttons on opposite sides of a release pushbutton are individually depressible to operate a respective set of normally open contacts to a closed position. A rotatably mounted latch is spring biased against a medial surface of one of the pair of pushbuttons to engage a latch surface upon depression sufficient to close the contacts. The release pushbutton overlies a lever arm of the latch and depression of the release pushbutton rotates the latch free of the latch surface to release the depressed pushbutton. A solid bar interlock is pivotally mounted on the release pushbutton, and opposite ends of the interlock extend into the paths of the pair of pushbuttons. Latched depression of one outer pushbutton draws the release pushbutton down close to the latch lever arm, whereupon little movement of the other outer pushbutton is required to operate the latch to a release condition. Simultaneous depression of both outer pushbuttons is blocked by a limit stop prior to closure of either contact set.
