ABSTRACT:
A time delay type of switch actuating mechanism is shown that can be assembled for either an "on delay" or "off delay" operation. A pair of contact carriers are mounted for linear motion, and a pivoted rocker member is joined between them for coordinating their movements. The rocker member has a lost motion connection with each contact carrier, and a catch is provided to restrain movement of the rocker and contact carriers until a timer performs a timing function. At the end of the timing interval the catch is released to permit a loaded spring to move the contact carriers and rocker to complete a switching function that is time delayed.
