ABSTRACT:
A power supply control system of an installation including at least two devices having respectively electric circuits, e.g. a tuner, a tape deck and a main amplifier, which comprises a manually operated first switch adapted to generate a first control signal when closed; a control signal generating circuit adapted to generate a second control signal when activated; a manually operated second switch adapted to activate the control signal generating circuit when closed, the second switch being preferably a power supply switch of one of the devices; first switching means provided between the electric circuit of second one of the devices and a power supply and adapted to be rendered conductive in response to the first control signal from the switch; and second switching means provided between the electric circuit of third one of the devices and the power supply and adapted to be rendered conductive and nonconductive respectively by closing and opening of the manually operated first switch, the second switching means being further adapted to be able to turn nonconductive in response to the second control signal so that the supply of power to one of the devices can be controlled synchronously with the supply of power to another of the devices.
