This article describes a design and implementation of switch,with short-range infrared remote control.Utilizeing a dedicated infrared remote codec IC chip:PT2262-IR(infrared dedicated models),PT2272-L4 (output latch),38KHZ center frequency infrared receiver CHQ1838 and other simple common components,etc, multi-address use and multi-function four-way switch remote control function can be accomplished. The system achieve the wireless control of switch by transmitting and receiving 38KHZ infrared signals ,which advantages are small size,low cost,multi-channel control,with the transmitter and receiver display,multi-address allocation.
