ABSTRACT:
An electric bypass switch for connecting and disconnecting an electric apparatus such as a voltage regulator with respect to a power system includes a pair of spaced insulators on each of which a pair of conductive terminals are mounted, one pair of terminals being adapted for connection to the apparatus and the other pair of terminals being adapted for connection with the infeed and outfeed conductors of an electric power line respectively, a pair of hinge contacts hingedly mounted respectively on one pair of the conductive terminals, a pair of jaw contacts mounted respectively on the other pair of conductive terminals, a unitary switch blade having a pair of concentric conductors which are separated by mechanically sturdy insulating material and arranged with the hinge ends thereof connected respectively with the hinge contacts and the swing ends of the switch blade conductors being engageable and disengageable with the jaw contacts respectively, a bypass conductor electrically connected with and pivotally mounted on one of the jaw contacts together with a pin mounted on a switch blade for disjointably engaging the bypass conductor for causing the bypass conductor to engage and disengage the other of the jaw contacts in coordination with opening and closing movement of the switch blade respectively.
