Abstract: A timing attachment for a relay which may be programmed to provide an ON DELAY or an OFF DELAY operation of a pair of switches with each switch having either normally open or normally closed contacts. The attachments includes a bellcrank having a lever arm actuated by the relay. The bellcrank has a ball and socket type connection in either of two sockets in a slider to program the attachment to operate in the time delay after energization mode or a time delay after deenergization mode when a housing enclosing the slider is mounted in either of two positions on a support for the bellcrank. The attachment includes a pair of switch cartridges which are insertable in either of two positions in sockets selectively to provide a normally open or normally a closed contact operation when the relay is energized and deenergized.

Abstract: A timing attachment for a relay that is programmable to provide an ON Delay or an OFF Delay operation of a pair of switches having either normally open or normally closed contacts. The attachment includes a housing that is mountable in either of two positions on an assembly that is attached to the relay to program the OFF and ON Delay timing functions and indicia on the switches that indicate the contact operation of the switches when the switches are inserted in sockets in the attachment. A cover for the attachments has openings there through that expose indicia on the switches indicating the normally open and normally closed operating condition of the switches when the switches are inserted into the sockets and a slider that is movable along a rear surface of the cover to positions indicating the programmed operation of the attachment and the mode of operation of the switches when the attachment is mounted on the relay.
