Abstract
A lighting dimmer (52) adaptable to four wiring configurations is capable of use in serial or parallel lighting circuits and in place of two-way or three-way switches. The dimmer operates in series when one active input wire (H) is connected and in parallel when two active input wires (H, N) are connected. The dimmer is operated in place of a two-way switch by connecting one output wire (DH1) and in place of a three-way switch by connecting two output wires (DH1, DH2).
