Abstract: A transfer switch including: a bus bar; a track parallel to the bus bar; a first power source connection proximate to the track; a second power source connection proximate to the track offset along the track from the first power source connection; a conductive core slidably coupled to the track, wherein the core includes a deformable array of conductive sections and the array includes contacting surfaces on opposite sides of the array; wherein the conductive core has a first position providing a conductive coupling between the bus bar and the first power source and a second position providing a conductive coupling between the bus bar and the second power source.

Abstract: In a system with two electronic panels arranged with a plurality of busses between them, the removal of one of the electronic panels exposes the live busses to a user. To shield the user from the exposed busses, a mechanism operates shutters to close and cover the busses. The mechanism operation can be based on the rotation of a cam supporting the shutters in the open position. A manual override allows the shutters to be kept in the open position even when the busses are exposed due to the removal of an electronic panel.
