ABSTRACT:
An electrical box is provided at the outer end of an electrical power cable of the type that supplies power to aircraft parked at an airport, which enables rapid replacement of damaged switches in a compact and watertight arrangement. The electrical box includes a main connector assembly which has a plurality of conductor socket terminals connected to conductors in the cable, and a switch assembly which includes a plurality of switches. The switch assembly fits into a recess in the main housing, and includes projecting pins connected to the switches and which are received in corresponding conductor socket terminals on the main housing. Not only can switches be easily replaced, but the arrangement avoids the need for a bulky connection box where wires of switches are connected to free lengths of the conductors. The switch assembly includes a circular projection from which the pins project, the circular projection including a sealing ring which seals to a corresponding circular recess in the main housing.
