摘要： 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.

摘要： An improved movement for a time delay relay cooperates with an electromagnet and a timer to provide either "On Delay" or "Off Delay" operation of the relay contacts. The movement has an elongated operating plunger that is movable in forward and backward strokes, a latch, and a contact actuator coupling the latch to the relay contacts. A pair of springs are disposed in a spring cage formed in the actuator and at least one spring-compressing flange is carried by the plunger and disposed between the springs. In the on delay mode of operation, one spring is loaded against the actuator upon a forward stroke of the plunger. In the off delay mode of operation, the other spring is loaded against the actuator upon a backward stroke of the plunger. The latch is restrained upon the movement of the plunger to load one of the springs, and is subsequently released from its restraint after a time delay to operate the relay contacts with spring action.
