Abstract

An electrical switch includes a housing having first and second input connections for electrical connection to a voltage source and the housing further has first and second output connections for electrical connection to an electrical device. The second input connection has an electrical connecting part for connection to the second output connection. The electrical switch also has an operating element which can be moved manually and at least one contact system which includes a fixed contact and a contact rocker. The contact rocker has first and second lever arms and a rotating bearing. The first lever arm is in communication with the fixed contact. The fixed contact is directly connected to the first input connection. The operating element, during its movement, acts upon the second lever arm in such a way that the first lever arm can be placed against the fixed contact in order to close an electrical connection of the contact system. The electrical switch further has a current carrying rail, having first and a second ends, located in the housing for establishing an electrical connection to the first output connection. The first lever arm is biased by a spring force in a closing direction toward the fixed contact. The rotating bearing is arranged on the current carrying rail near the first and second input connections. The current carrying rail extends from its first end from the region between the first and second input connections to its second end in the region of the first output connection and is located in approximately the center of the housing and passes through the housing in a direction approximately at right angles to the direction of movement of the operating element.
