Abstract
An ultrasonic remote controlled switching device having very low power consumption is shown. The device is capable of switching high power and/or generating a power pulse for operating associated electrical control devices. The switching device responses to ultrasonic wave generated by a remote hand-held transmitter unit to change its state from ON to OFF or vice versa and simultaneously generates the desirable power pulse. The remote switching device is suitable for use in remotely controlling the operation of a natural gas fireplace.
