ABSTRACT:
A non-fused electrical slide switch. A handle assembly is operatively connected to a base, between on and off positions, and movable relative to a cover. The base has two pair of raised landings rising above four contact strips. Each pair of raised landings are disposed between one load and one line contact strip of the four contact strips and between the one load contact strip and partitions of the base, respectively. A shoe assembly includes a pair of contact shoes and at least one pair of springs biasing the pair of contact shoes. Depending portions of each contact shoe are in direct contact with associated load and line contact strips allowing electrical communication therebetween. The two pair of raised landings prevent arcing as the handle assembly traverses the on/off positions by raising the depending portions of each contact shoe immediately after they leave contact with the associated load and line contact strips.
