Abstract: A lighting fitting for hazardous areas comprises a central hub. Each lateral face of the hub incorporates a connector into which a module containing control equipment for the fitting may be housed. A further connector is disposed in the underside of the hub to receive the lamp. The hub houses a microswitch, which may be flameproof, through which the power supply to the connector is controlled. Springs in the connectors, a locking plate and an actuator shaft combine to prevent operation of the microswitch unless and until a lamp and all modules are connected to their respective connectors. This construction aids manufacturing flexiblity and economy and enhances safety.
