ABSTRACT:
A pushbutton switch structure characterized by a pushbutton switch handle and a plurality of switch blocks mounted in tandem, each switch block having an operating plunger for simultaneous operation by said switch handle carrier means associated with the plunger for carrying movable contacts between open and closed positions of stationary contacts, the plunger and carrier means having spaced complementary surface means engageable during movement of the plunger, whereby actuation of the pushbutton handle effects simultaneous operation of all of the plungers and a delay of movement of movable contacts from the normally closed position.
