ABSTRACT:
An electrical switch wherein a body of the switch supports a rotor. A contact is movable with the rotor relative to first, second and third fixed contacts supported by the body. An operating lever extends from the body transverse to the rotor axis and is coupled to the rotor to transmit rotational movement of the lever about its longitudinal axis to move the rotor about its rotational axis. Annular movement of the lever about the rotor axis is also transmitted to move the rotor about its rotational axis. A first detent defines first, second and third predetermined rotational positions of the lever about the lever longitudinal axis. A second detent defines first and second predetermined angular positions of the lever about the rotor axis. The first, second and third fixed contacts, the spacing between the first, second and third rotated lever positions, and the first and second lever angular positions are so arranged that in the first, second and third lever rotational positions respectively, with the lever in its first angular position, the movable contact is respectively, clear of the fixed contacts, in engagement with the first fixed contact, and in engagement with the first and second fixed contacts. However, in the first, second and third lever rotational positions with the lever in its second angular position, the movable contact is respectively, clear of the fixed contacts, in engagement with the first and second fixed contacts, and in engagement with the first and third fixed contacts.
