When the electrical load is electrically disconnected from the power source, the toggling results in the electrical load being electrically connected to the power source. When the electrical load is electrically connected to the power source, the toggling results in the electrical load being electrically disconnected from the power source.

Abstract: An electrical switching device and method are disclosed. The electrical switching device can include two movable contacts. During opening of the switching device, the two movable contacts move in a first direction until one of the movable contacts engages a blocking member. The other movable contact continues in the first direction, effecting opening of the switching device. In a particular implementation, the movable contact that engages the blocking member “bounces” in a second direction after contacting the blocking member. This causes the contacts of the switching device to be separated very quickly, reducing electrical arcing during opening of the switching device.
