ABSTRACT:
An engine starter circuit for an automotive vehicle provided with an automatic transmission such that an engine can be started only when the gear selector lever is in the park or neutral position, in particular, only when the gear selector lever is securely shifted into the park position. The engine starter circuit according to the present invention comprises a redundant park-position detection switch in addition to an engine-starter switch and an inhibitor switch including a park-position detection switch and a neutral-position detection switch, so that the pseudo-parking position caused by a mechanical play in a linkage mechanism can be reduced, with more reliable detection of the park position. The redundant park-position detection switch is a pin-actuated or a body-actuated selector microswitch positioned with respect to the gear selector lever of the automatic transmission and so constructed as to reduce the mechanical play inherent in the detection of park-position.
