Abstract
An electronic circuit arrangement automatically provides an energizing current to a solenoid for ejecting a plug from an outlet coupled to a source of supply voltage upon substantial cessation of current flow being drawn by an appliance by way of the plug while the supply voltage is present. The energizing current is controlled by a controlled switching device. An optional keyed plug is utilizable for selectively enabling operation of the solenoid.
