ABSTRACT:
A key-manipulatable switch for a motor vehicle ignition system having a housing and a cylinder mounted within the housing for rotational and axial movement with respect thereto includes cooperating components which prevent the rotation of the cylinder counterclockwise from a first rotational position to a second rotational position unless the cylinder is in a preselected axial position with respect to the housing while permitting unrestricted clockwise rotation of the cylinder to any of several rotational positions. In one embodiment, the cylinder includes a spring-biased stop member which cooperates with a lug-like projection defined by the housing.
