Abstract
An adjustable ignition shut-off switch for lawnmower engines is disclosed in which a tab attached to the bale lever moves a resilient switch contact away from a ground terminal when the lawnmower is in its run position. When the bale lever is released, the tab disengages the switch contact, permitting the resilient switch contact to make an electrical connection with the ground terminal. Since the switch contact is also electrically connected to the engine ignition system, ignition pulses are grounded to stop the engine when the switch contact is electrically connected to the ground terminal. The height of the tab is adjustable so that the shut-off switch may be adapted to different lawnmower applications.
