In an ignition switch for use in combination with a key operated steering column lock for a road vehicle, a movable contact member is mounted on a rotor for rotation with the rotor within the switch casing. First and second movable contact arms are carried by the rotor and are engageable with the contact member. Co-operating cam means on the casing of the switch and the first and second contact arms control engagement of the first and second contact arms with the contact member during rotation of the rotor relative to the casing, the first and second contact arms and the contact member defining the movable contacts of the switch.
