Abstract
A wall socket is adapted to be flush-mounted in a wall terminal box. The base of the wall socket comprises a base portion, which is flush-mounted in the wall terminal box and supports connector terminals for an alternating voltage available in the wall terminal box, as well as a surface-mounted base portion, which is located outside, and is laterally offset in relation to the opening of the wall terminal box and which supports at least one low-voltage socket (31) for a direct voltage. A surface-mounted cover (40) encloses not only the opening of the wall terminal box (10) but also the surface-mounted and laterally-offset base portion, and further is formed with one or more openings giving access to the low-voltage socket. A transformer and rectifier element arranged in the wall terminal box has an alternating voltage side for connection to the alternating voltage, as well as a direct-voltage side for emitting step-down transformed and rectified voltage to the low-voltage socket (31).
