Abstract
A foot-pedal switch for electrically connecting two conductors includes a conductive base plate connected to one of the two conductors and having a bottom surface for resting on a horizontal surface, a rear end having a first portion of a hinge assembly, at least one non-conductive spring, and a first conductive contact point at a front end thereof. A conductive top plate is connected to the other conductor, a rear end having a second portion of the hinge assembly, and a second conductive contact point at a front end thereof. A non-conductive hinge pin assembly pivotally connects the first and second portions of the hinge assembly mutually and non-conductively together. The top plate rests on the springs such that the first and second contact points are electrically and mechanically separated until pressure is applied to the top plate to deform the springs until the contact points electrically connect.
