A first breaker is adapted to be connected to an external source of electrical power, and a second breaker is adapted to be connected to an electrical generator. The first breaker is in an on position when the second breaker is in an off position, and the first breaker is in an off position when the second breaker is in an on position. The breakers are in combination with a toggle adapted to simultaneously operate the first breaker and the second breaker. The first breaker has a first breaker hole, and the second breaker has a second breaker hole, where the first breaker electrically connects an external power transmission to a breaker box, and the second breaker electrically connects a generator to the breaker box. The toggle comprising an integral bar with a first toggle hole through the toggle, and a second toggle hole through the toggle, such that the first toggle hole and the second toggle hole are longitudinally spaced whereby the first toggle hole registers with the first breaker hole while the second toggle hole registers with the second breaker hole. A first bolt extends through both the first toggle hole and the first breaker hole, and a second bolt extends through the second toggle hole and the second breaker hole, such that when the first breaker is turned to an on position, the toggle simultaneously turns the second breaker to an off position, and when the first breaker is turned to an off position, the toggle simultaneously turns the second breaker to an on position.

A circuit breaker having a mechanical switch introduced into a main current path, which comprises a fixed contact and a moving contact connected to a movably mounted contact bridge.

An exhaust gas module for an electrical switch, which has outlets for switching gases on its output side and/or its input side. The exhaust gas module can be mounted on the electrical switch, such that the switching gases are directed into an exhaust gas channel of the exhaust gas module. The exhaust gas channel deflects the switching gases substantially at a right angle and the exhaust gas channel can cooperate in a modular manner with a neighboring exhaust gas channel of a neighboring exhaust gas module in order to bring together the deflected exhaust gases.

A rotating dual break point contact includes a rotor support, a first shaft, a second shaft, a third shaft, a first connection rod, a second connection rod, a contact bridge and a contact spring. The contact bridge is provided in the rotor support, and the contact bridge rotates relative to the rotor support by means of the first shaft, the second shaft, the third shaft, the first connection rod and the second connection rod. The contact bridge rotates between an initial pressure position and a maximum repulsion position. A single contact spring is mounted on one side of the contact bridge and is located in the rotor support.

The application relates to a power switch for breaking an electrical circuit when current and/or current time span threshold values are exceeded, including an energy converter, which on the primary side is connected to the electrical circuit, and on the secondary side provides an energy supply for at least one control unit of the power switch.
