The digital code control switch digital woven decoder MC145026/MC145027 and the mini radio transceiver module M303S/M303R is as shown. When you press the transmitter button SA, the circuit gets the electricity to start working, the serial coding signal is output from the pin-15 of MC145026 and then it is sent out by the M303S launch module. Receiving module M303R of the receiving circuit receives the serial coding signal, then modulates the encoded signal and sends it to the MC145027 decoder, when the decoder's address and coding are the same, MC145027's decoding effective instruction end outputs the high-level pulse signal, the transistor VT conductsand drives the relay to close, also it completes the switch control function.
