The infrared remote control switch circuit which uses the infrared receiving and decoding remote control circuit is as shown in the figure, the transmission circuit is composed of the astable multivibrator (composed of the 555). The oscillation frequency is about 38 kHz. The receiving circuit uses the special infrared receiving and decoding integrated circuit μPC1373H, the receiving circuit has the automatic brightness control circuit (ARC), so it has the accurate response to the infrared signals which have the different intensities and same frequencies. At this time, the output port has the low level to control the executive circuit.
