Abstract
A switch controller having a housing cover with a central ridge and opposed top surfaces which incline downwardly away from the central ridge. The top surfaces also incline on progressing from one end of the housing to the opposite end. A pair of footpads are mounted on the upper surface of the housing and incline consistently with their associated portions of the housing surfaces. The under surfaces of the footpads have spaced apart contact points thereon. Underlying the contact points are associated switches which are actuated by pressing downwardly on selected regions of the footpads. Fulcrum means are disposed between the associated pairs of contact points and switches to inhibit simultaneous actuation of adjacent switches.
