Abstract:
1. A portable lighting device comprising: a light source; lighting control circuitry; first and second power terminals adapted to receive a battery power source; first and second electrical connections between the lighting control circuitry and the first and second power terminals; a third electrical connection between the second power terminal and the lighting control circuitry; a switch adapted to selectively connect and disconnect the third electrical connection, wherein the lighting control circuitry is adapted to operate the light source in response to a signal received over the third electrical connection in response to the switch, wherein the first and second electrical connections are adapted to provide constant power to the lighting control circuitry while the battery power source is connected to the first and second power terminals regardless of operation of the switch; a conductive housing, wherein at least a portion of the third electrical connection is provided by the conductive housing; and a non-conductive sleeve nested in the conductive housing and adapted to insulate at least a portion of the second electrical connection from the conductive housing.
