Domestic lighting remote control unit - has each consumer connected via control unit to supply line and to parallel, common data line

摘要

Unit for remotely controlled switch-on and switch-off of electrical consumers connected to an electrical supply line, e.g. the illumination facilities of a private dwelling is designed to allow individual control of spot-lights, wall-lights etc. without incurring high design costs. Thus each consumer (1) is connected to the supply line via a control unit (10) and to a data line (DL) common to all the consumers and in parallel with the supply line. A command unit (20) is connected at least one point on the data line and supplies coded data into the data line via a keyboard.
