Abstract

A key-operated ignition device which prevents an engine starter from being driven while the engine is already running, so to protect the starter and engine from damage. The device comprises a key-operated rotor disposed in the device for turning a locking cam via a coupling plate to shift an ignition switch between off, on and start positions. A sliding member is selectively movable between first and second positions by a restriction plate, wherein when the sliding member is in the first position the rotor may be turned from the on position to the start position and when the member is in the second position, the rotor is prevented from again turning from the on position to the start position, without first turning to the off position. The restriction plate also prevents the rotor from being directly turned from the off position to a lock position.

Dependent claims

A key-operated ignition device for driving an engine starter comprising:

a rotor operatively turned by a key, said rotor being disposed in a case of said device;
a rotor driven coupling plate fitted on one end of said rotor;
means for selectively shifting an ignition switch between switch-off, switch-on, and start positions, said shifting means being coupled to said coupling plate;
a sliding member disposed in said case, said sliding member being selectively moved between first and second positions along a longitudinal axis of said case;
restriction means in cooperation with said shifting means for moving said sliding member between said first and second positions, wherein when said sliding member is in said first position said rotor can be turned from said switch-on to said start position, and when said sliding member is in said second position said rotor is prevented from again turning to said start position without first turning from said switch-on position to said switch-off position.
