ABSTRACT:
A multi-phased switch support base including a molded top cover and a molded bottom base each having interior and exterior walls which divide the interiors. When assembled together the base is divided into compartmentalized arc chambers which function to isolate each line contact and each load contact of each phase of the switch from each other as well as from each other line and each other load contact of each of the other phases of the switch. A multiplicity of unique snap-in arc chutes and baffles to help control and extinguish the arc generated during disconnect operations of the rotor from the stationary contacts are provided in each arc chamber.
