Self-cut-off power switch for a remote controlled electronic equipment

A power switch circuit for a remote controlled electronic equipment comprising;

• A. a remote controlled electronic equipment,
• B. a remote control unit for wirelessly transmitting a signal to control turn-off of a power to said remote controlled electronic equipment,
• C. a control unit for wirelessly receiving said signal from said remote control unit during operating condition of the control unit to control the turn-off of the power of said electronic equipment,
• D. a switch means having turn-on and turn-off states controlled by said control unit,
• E. a manual means which is normally open but temporarily short-circuits said switch means when manually operated, and
• F. a means for supplying said power through said switch means to said electronic equipment and said control unit to put them in their operating conditions,
• said control unit including;
• a. a holding means for holding said switch means at its on-state, and
• b. a stop means for allowing said holding means to hold said switch means until the power turn-off signal from said remote control unit is received and stopping the hold function of said holding means when said power turn-off signal is received,
• whereby the operating conditions of said control unit and said electronic equipment, which have been attained by manually operating said manual means to short-circuit said switch means, are switched to their non-operating condition by the power turn-off control signal from said remote control signal, said non-operating conditions being non-restorable unless another manual operation is intervened.
