Abstract
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.
