ABSTRACT:
A battery housing is formed by a pair of side walls, a top wall and a bottom wall. One end of the battery housing is closed and an opposite end is open. The housing forms a compartment adapted to receive through the open end portion a multicelled planar battery of the type employed in a cassette film pack conventionally used in a self developing photographic camera. A pair of electrically conductive leaf spring terminals are secured to the battery housing top wall. Each of the leaf spring terminals has a first contact end portion positioned within the compartment and a second contact end portion projecting out of the compartment. A sliding switch is mounted on the battery housing. Electrical leads connect the leaf spring terminals to an electrically operated device and the switch. The electrically operated device has a voltage rating which corresponds to the voltage of the multicelled planar battery, for example, six volts. In a preferred embodiment, the electrically operated device is a light bulb mounted in the socket of a lens. The switch is operable between a first position and a second position to open and close the circuit and thereby illuminate the light bulb when desired for use as a flashlight. With this arrangement a cassette film pack is reusable after its use in a photographic camera as an energy source.
