  • Electrical switching device
    Patent number: 7435923
    Abstract: A switch having an actuating handle, a restoring mechanism, a contact carrier, and a rocker. The handle is rotatable to be movable upward and downward and moves downward in response to being actuated. The restoring mechanism is movable upward and downward and is biased to move upward. The handle forces the restoring mechanism to move downward in response to being actuated. The carrier is displaceable between two positions. The rocker is rotatable and an end of the rocker facing away from the swivel axis is engaged with the carrier. During downward movement the restoring mechanism swivels the rocker in a first direction thereby causing the rocker to displace the carrier from one position to the other. During upward movement the restoring mechanism swivels the rocker in an opposite direction thereby causing the rocker to displace the carrier back to the original position.
