ABSTRACT:
A high voltage switch has a molded plastic support base which carries contact terminals at its opposite ends and on the front surface of the base. Switch contacts are connected to the terminals. The support base is hollow and its interior and exterior surfaces are slotted or projections are added to increase electrical creepage from the switch support to the switch contacts. The support base has openings for receiving elongated bus terminals to allow rear connection of the switch terminals rather than front connection to the front switch terminals. A rotatable operating shaft is mounted at the rear of the base and connected to the switch blade by insulation operating links. A suitable operating mechanism is fixed to the operating shaft at one end thereof.
