Abstract: An ignition switch includes a casing and a rotor mounted for rotation within the casing from a stable first position to a stable second position and from the stable second position to an unstable third position from which it is resiliently urged back to the stable second position. An arcuate cam track is provided on the inner surface of the casing and includes surfaces which extend generally at right angles to the axis of rotation of the rotor. A latch member is rotatable with the rotor and includes a finger which extends radially into engagement with the cam track, a resilient member acting on the latch member urging the finger into engagement with the cam track and being capable of urging the finger radially outwardly when the finger is moved radially inwardly by the cam track during rotation of the rotor. The arrangement for the finger and the cam track is such that the rotor is prevented from movement from its second position to its third position unless the preceding movement of the rotor was from its first position to its second position.
