Abstract
An electrical switch comprising a casing and a rotor supported within the casing for rotation about an axis. The rotor has a first surface extending around the axis and a second surface extending transversely of the axis. A moving contact is mounted on the rotor for rotation therewith, which has first and second inter-connected parts adjacent the first and second rotor surfaces respectively. A plurality of fixed contacts is located laterally of the rotor for short-circuiting by the moving contact whereby the switch is closed. At least one of the fixed contacts has first and second inter-connected parts bearing resiliently against the first and second rotor surfaces respectively for contact with the corresponding fist and second moving contact parts according to the angular position of the rotor.
