Abstract
An electrical test switch having a pair of spaced conductive rotors provided with matching cut-outs, the rotors being movable between a 'normal' position and a 'test' position. At least two spaced conductive contacts extend within a region between the rotors. The cut-outs and the conductive contacts are arranged so that the contacts wipe against the rotors when the rotors are in the 'normal' position and at least one of the spaced contacts is aligned with the cut-outs when the rotors are in the 'test' position. A shaft locks the switch in the 'normal' position until manually released.
