Abstract
A recharging system for a battery operated tool such as a lawn mower. A slidable cover is used which is movable between an open position and a closed position. The slidable cover alternately exposes a receptacle adapted to receive a removable fuse key and an electrical connector adapted to receive an electrical power cord. The receptacle and the electrical connector are longitudinally aligned with the cover so that for the cover to move to the open position and expose the electrical connector, the fuse key must be removed. The receptacle is electrically connected in series with an activation switch, the battery and the electric motor to form a motor circuit. When the fuse key is removed to expose the electrical connector, the motor circuit is broken which prevents the electric motor from being activated whether or not the activation switch is engaged. When the cover is moved to the closed position exposing the receptacle, the fuse key may be inserted into the receptacle, completing the motor circuit enabling the activation switch to activate the electric motor.
