Abstract
A pair of sliding plates engage respective moveable structures such as the actuating lever of an existing wall switch and are housed in a dual-gang or larger cover plate body. A cam, preferably formed on an edge of each sliding plate, engages a cam follower on respective resilient conductive contact blades; a pair of contact blades being preferably positioned between edges of the sliding plates. Movement of either electrical switch operating levers through an intermediate position causes a respective contact blade to engage and form a momentary electrical contact with the other contact blade with a bi-directional wiping motion. Both contact blades may be simultaneously urged toward the other by respective cams.
