Abstract: A two-legged contact spring with a spring base, at least one contact leg and a U-shaped bend is provided as a short-circuit bridge for the connection of two contact elements. The contact leg is freely yielding and has a projection which contactingly rests directly at a transitional region of the contact element. Therefore, the spring work is carried out exclusively by the short-circuit bridge. The spring form and position of the contact point ensures an optimal spring action at low operating forces.

Abstract: A one piece jumper power cord molded out of rubber or some other insulating material. The one piece power cord conforms to the rear shape of a vertical stack of electronic devices that it interconnects. By keeping the power cords short and properly shaped, power can be jumpered from a lower device housed in a lower enclosure of the vertical stack to an upper device housed in an upper enclosure without a loose jumper cord dangling therebetween, wasting space and providing a possible hazard for passing objects or persons to catch on.
