A transmitter, for electrical appliance control by transmitting digital control signals on a power main, comprises two releasably connected parts, a first part comprising m actuators to initiate the generation of m control signals, and the second part containing a generator for the control signals, and a selector for selecting m out of n control signals. The selector is hidden by the first part when the parts are joined together and may be adjusted to select different groups of m control signals from the n possible signals. All n control signals can be produced, in groups of up to m signals for each condition of the selector. A monitor is also provided to monitor the main in order to achieve transmitter queueing dependent upon the selector settings at the transmitters.

A transmitter for controlling n slave units by means of a digital control signal containing an area code common to said n slave units, an address for at least one of said n slave units and a command, the transmitter comprising: first means for generating an area code; second means for generating selectively any one of n addresses for respective ones of said n slave units; third means for generating a command; m (1) actuator means coupled to the first, second and third generating means such that a single actuation of one of said m actuator means causes the generation of a digital control signal comprising said area code, an address selected from said n addresses, and said command; and address selector means presettable to any one of a plurality of conditions, each of which condition presets a group of m addresses where m is less than n, for defining which addresses constitute said group of m addresses; whereby all n slave units, in sequence of operation of said selector means, are controllable by said actuator means of said transmitter in groups of up to m slave units for each condition of the selector means.
