ABSTRACT:
A three position slidable switch for use in a portable, rechargeable electrical device includes ON, OFF, and CHARGE positions. In the ON position a rechargeable battery is coupled in circuit with the device for the operation thereof. In the OFF position the battery is electrically decoupled from the device which is in an OFF state. In the CHARGE position the battery is coupled to a pair of prongs adapted to be plugged into an electrical outlet. Displacement of the switch to the CHARGE position rotates the prongs to an extended position to permit the battery to be recharged by means of a conventional AC outlet. In the ON and OFF positions of the switch, the prongs are retracted within the switch assembly. The switch includes detent means in each of the three aforementioned positions to reduce the possibility of inadvertent re-positioning of the switch and to provide a tactile indication to the user of the switch position. In one embodiment the prongs are spaced apart in the direction of elongation of the device and in another embodiment the prongs are spaced apart in a direction perpendicular to the direction of elongation of the device.
