ELECTROMAGNETIC RELAY WITH REVERSIBLE SWITCH MODULES

A relay having switching modules which permit the switching functions of the relay to be easily converted to provide normally open or normally closed contact functions without disturbing the wiring to the relay. The switch modules are mountable in either of two positions in individual readily accessible sockets in the relay and are actuated by a lever arrangement which acts as a stabilizer and stroke multiplier. The stroke multiplying action of the lever arrangement permits the magnet to have a small air gap and to operate with a reduced inrush current. The relay also includes a pair of plungers which are actuated by the levers and act as indicators and load balancers to prevent the switch modules from providing undesired overlapping contact functions.
