Abstract: radio frequency technology information technology as one of this century’s most promising, has been the industry's attention。 The technique utilizes non-contact radio frequency two-way communication mode can be automatic target recognition and access to relevant data， with high precision, strong ability to adapt to the environment， strong

anti-interference， quick operation and many other advantages.

Radio remote control is the use of radio frequency signals to remote institutions to control a remote control device， this paper has a variety of modern household appliances， design a multiplexer can be controlled with a wireless remote control switch electrical appliances。 The design method of four wireless remote control switch system, and the structure and working principle of the system has been described in detail。 The system uses the received signal decoder chip decodes this paper has a variety of modern household appliances, designed a can control multiple appliances wireless remote control switch. This design uses 315M radio—controlled frequency stabilization components and other peripherals。 Remote control switch assembly, respectively， can switch 220V Quad appliances can also be connected to each relay changeover contact with 220V draw off the strips on the PCB，using only the relay contact output to switch or other control circuitry。The wireless remote control switch can control four digital circuit， in short distance (≤10m） within, without aligning with the electrical pressing a remote control button， you can achieve multi-channel remote power supply circuit is turned off and purpose， It applies not only to the average family, but also for major hotels, restaurants， luxury villas and other places use。Radio remote control is the use of radio frequency signals to remote institutions to control a remote control device。

After the test verification, the wireless remote control switch is easy

to operate, reliable， and meet the design requirements. Study results have

important implications for the promotion of intelligent household appliances.
