Abstract

An interlock mechanism for an ignition switch has a pawl 23 which is carried by the rotor (not shown) and which can be arcuately moved over the base 14 of a housing 12 between an OFF position and a START position. In the IGNITION position, the base 14 has a recess 15, 16 which can receive the pawl 23 on return from the START position and from which the pawl can be disengaged by movement only up a ramp 17 in the direction away from the START position. An arcuate spring wire 20 overlies the recess 15, 16 and prevents the pawl 23 dropping into the recess when moving from the OFF position to the START position. When in the START position, the pawl 23 engages the free end of the spring wire 20, and, on subsequent return from the START position, causes the spring wire 20 to expose the recess 6 for reception of the pawl 23. <IMAGE>
