ABSTRACT:
A high-voltage switching device is provided having an insulating base member mounted to a panel such that a wiper arm assembly of the switching device is accessible from the front of the panel for pivoting a switching member between open and closed positions. Preferably, the switching member is a conductive rod having a portion coiled about a primary terminal assembly of the switch such that a first end of the conductive rod may be pivoted about the axis of the coiled portion between the open and closed positions. Although the switch is intended for high-voltage applications, the conductive rod is of sufficiently small gauge so as to allow for the manual pivoting of the rod without the need of leveraging linkages. The insulating base member of the switching device provides effective electronic isolation of the terminal assemblies and the conductive rod from one another and from the ambient environment of the switch such that a protective insulating housing is unnecessary.
