Abstract

A power control apparatus for applying or removing power to an electrical appliance that is remote with respect to the user. A power subunit which is connected to the appliance receives a signal from a remote control means to either apply or remove power to the appliance.

Claims

1. A power control apparatus for applying or removing power to an electrical appliance comprising in combination:

a first power control means connected to input power lines to receive the power thereon, said input power lines being connected to a wall socket, said first power control means comprising a normally closed momentary action switch, said switch being serially connected in one of said input power lines, and,

a second power control means connected to said wall socket by means of an electrical plug, said second power control means including a parallel pair of electrical wires from said electrical plug to an electrical socket mounted thereon, said second power control means comprising a solenoid means connected between said parallel pair of electrical wires, and a first and second switch means, said first switch means connected in one of said electrical wires between said electrical plug and said solenoid means, said second switch means connected from the junction of said first switch means and said solenoid means to said electrical socket, said electrical socket receiving the input plug of an electrical appliance which is to be controlled, said first switch means comprising a normally closed momentary action switch, said second switch means mechanically connected to the plunger of said solenoid means by a mechanical linkage, said mechanical linkage connected to the frame of said second power control means by a spring, said second switch means having a first and second switch position, said solenoid means holding said second switch means in said first switch position, said solenoid means responding to a temporary current interruption by allowing said second switch means to move to said second switch position, after said current interruption said solenoid means returns said second switch means to said first switch position, said second switch means being switched between an on state and an off state in response to said solenoid means reaction to said current interruption.

2. A power control apparatus as described in claim 1 wherein said first power control means switch is manually operated to cause said current interruption.

3. A power control apparatus as described in claim 1 wherein said first switch means is manually operated to cause said current interruption.
