ABSTRACT:
A device for closing an ignition-enablement switch only if a drive control is in neutral position includes a stop member, a switch mount and a closing member each biased toward its position of engagement with the stop member and movable to positions displaced therefrom, the switch mount having the switch on it such that it is closed by the closing member only when the closing member and switch mount are both in their stop-engaging positions, and an actuator mechanism movable with the drive control between positions displacing the closing member and positions displacing the switch mount, through a position displacing neither. The device may be integrated with the drive control, with major parts pivotable about the control axis. Or the device may be attached to the drive control by a link arm, with major parts pivotable about a separate axis.
