Abstract
An electrical logic circuit for incorporation in the common power supply system of an appliance including a plurality of electrical components which have intermittent power requirements comprises a system for designating the components as dominant and subsidiary components and circuitry to direct power to the dominant component preferentially and to the or a subsidiary component only in dependence on the instantaneous power requirement of the or a more dominant component. The logic circuit may include a standby facility to direct power selectively to the subsidiary component. The invention may be applied to an ironing system including a heatable iron as the dominant component and a heatable board as the subsidiary component.
