Abstract

PURPOSE:To attain a low price and simplification by forming the circuit using an insulation type switch. CONSTITUTION:The switch 201 is closed to permit a current to be flowed from a power source 207 through a load 205, the light emission diode 200 and a diode 204, and the light emission diode 200 to be turned ON. Meanwhile, when the switch 202 is closed, the current flows from a power source 208 through the switch 202, a load 206, the light emission diode 200 and a diode 203 to cause the light emission diode 200 to be turned ON. Further, the light emission diode 200 is turned ON, even the switches 201, 202 are closed at the same time.
