Abstract
An electrical switch assembly has an L-shaped housing with a base, an endwall and sidewalls which may be molded as a single piece. The endwall is provided with receiving slots for at least one metal plate serving as an arcing plate and with a central guide channel for a plunger arm which carries a contact blade. Stationary contact assemblies which have contact clamps are fit into receiving channels formed in the base and held down by hold-down rails alongside the channels. The bottoms of the channels include anti-turn channels for the heads of lug screws to facilitate assembly. A cover, which also has a centrally located guide channel for the plunger arm is fastened to the sidewalls. A baffle extends from the outer surface of the cover between the stationary terminal assemblies. A side shield extends from one sidewall. The exposed edge of the base remote from the endwall includes a lip with interlocking grooves adapted to slide into engagement with interlocking receiving grooves formed into the edge of the base under the endwall of an adjoining module and to snap into holding engagement by the resilient seating of a ridge on the edge of the base into a matching depression on the lip.
