A switch which permits the use of high contact spring force without the correspondingly high mechanism actuator force typically needed with a switch which utilizes a high contact spring force.

Switch contact configuration

An elevated neutral base for switches forming an open space for positioning of insulated electric wires.

Elevated neutral base for switches

Weatherproof enclosure

A Weatherproof Enclosure for electric load centers, switches, or other electrical components. The weatherproof enclosure includes a main enclosure base, two enclosure endcaps, and a hingeably mounted cover door for providing access to the interior of the weatherproof enclosure.

The invention provides a fuse clip guard and load shield for an electrical switch assembly of the type having a generally planar base and a pair of longitudinally extending substantially parallel insulating walls defining a longitudinally extending space for containing an electrical load terminal and a fuse clip. The fuse clip guard and load shield each have a lid portion pivotally mounted between the pair of walls and a gripping portion which may include a tab restricting movement of a fuse ejector handle.

Fuse ejector guard and terminal shield

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.
