ABSTRACT:
A low voltage distribution system comprises a two-conductor track of which one conductor is an outer conductor formed by its casing and the other conductor is an inner copper strip held by insulation. An adaptor can be fitted anywhere along the track and interlocked by closing pivoted members so that portions displace resilient arms outwardly to interlock lips of the adaptor with lips of the track. A fully rotatable contact assembly includes a center contact inside a sleeve contact as well as a lamp bracket which rotates as one with the contact assembly so that wires to the lamp never get twisted. For ease of mounting, a fixing device comprises a rotatable member which can be mounted to a support by a center screw and having a slot or opening to receive a connecting piece which is slidably connected to the back of the track casing by undercut tongue and groove.
