ABSTRACT:
A wireless power controller for use with a machine device to selectively connect and disconnect a machine device power source from the machine device includes a transmitter for transmitting an energy wave toward a receiving unit located at the machine device. The receiving unit has an electric switching circuit which is wired in series with the machine device power source and the machine device and provides electrical continuity through normally open transfer contacts are connected one-for-one with the voltage lines carrying power between the power source and the machine device and which contacts are closed during normal operation. The receiving unit senses an energy wave and causes the relay to become energized through operation of the switching circuit to disconnect power from the machine device.
