An emergency lighting fixture with backup battery power for illuminating aimable lamps or a plurality of lamps mounted in a single housing in response to loss of power. In the preferred embodiment, the lighting fixture has three independently adjustable lamps mounted within a single housing. The lamps are adjustable about vertical and horizontal axes for maximum aiming capabilities. The housing is preferably an explosion proof housing with a glass globe for mounting in hazardous locations or areas. The glass globe allows the lamps to be aimed through 360.degree. so that light transmitted by the lamps can be aimed to a specific area adjacent the lighting fixture. The lighting fixture also preferably has its backup batteries mounted within the housing along with a charger for maintaining the batteries at full charge.

Emergency lighting fixture, especially for hazardous locations

An electrical switch for hazardous environments includes a non-metallic terminal base supporting a plurality of stationary contacts. A non-metallic operator body has a radial wall and tubular outer wall extending from the radial wall. The outer wall has a free end coupled to the terminal base and defines a contact chamber inside of the operator body. The radial wall has a central passageway and a tubular inner wall extending from the radial wall toward the terminal base substantially concentrically to the outer wall and the passageway. A non-metallic operator member has an annular portion slidably received in the passageway between first and second positions, and has a radial portion extending from the axial portion with a tubular flange extending from it substantially concentrically to the axial portion. The operator member tubular flange is slidably received between and overlaps the inner and outer walls of the operator body in both of the first and second positions of the operator body. An operator is coupled to the operator member for movement between open and closed positions in response to movement of the operator member between its first and second positions. Movable contacts are mounted on the operator for simultaneous movement with the operator between positions engaging and disengaging the stationary contacts on the terminal base.
