Abstract
Abstract A portable power supply powers the light in a dental handpiece. The portable power supply includes a rechargeable battery for the electric power, and has connectors for connection to the handpiece and its fluid supply and exhaust. The connectors communicate with a manifold which has a port for connection of a pressure operated switch. The pressure operated switch operates the light so the light is illuminated only when the handpiece is operating.
