Electric appliances 11 to 1n such as electric heaters or electronic devices used in ordinary households have a frequency of 5 as described above.
It is driven by a so-called commercial power source whose value is 100 V at 0 or 60 Hz. Here, among these electric appliances installed in the home, electronic equipment such as a television or fluorescent lamps in lighting equipment operate on a commercial power source, but operate when the voltage is lowered to 10V. Disappear. That is, when the voltage as the power source is 10 V, the current flowing through these appliances becomes almost zero. On the other hand, in a motor device such as a refrigerator or cooler, current flows at the rated frequency even when the voltage drops to about 10 V, but it does not operate when a low voltage is applied at a high frequency such as 1 KHz due to the inductance component of the motor, Also in this case, the current flowing through this device becomes almost zero.

Therefore, when a high frequency low voltage of 10 V and a frequency of 1 KHz is applied to the electric appliances 11 to 1n by the oscillator 41, the appliances to be operated are an electric heater or a simple resistor such as an incandescent lamp without a dimming means. However, a large current flows as a drive current only in the device of these simple resistors. Thus, the current flowing through the simple resistor electric appliance flows through the resistance element 43 via the contacts 32 and 34, causing a voltage drop in this resistance element. This voltage drop is applied to the current detector 44, whereby the value of the current flowing through the resistance element 43 is detected.
