A programmable switching unit which may be incorporated in a switch for installation in a standard switch box, or into a single or multi-adaptor for connecting one or more appliances to a wall outlet, the unit being switchable between a first, learning mode, in which it updates a table of transitions between ON and OFF states of a controlled appliance over a first period, and a second, automatic mode in which it replicates the memorized transitions over a subsequent period or periods. The first period is preferably longer than the subsequent period or periods.
