The circuit consists of a single button infrared transmitter, infrared receiver, channel decoding circuit and control circuit. Among them, single-button infrared transmitter is controlled by a four - two input NAND gate 74HC00 composition. The circuit is shown as below: Infrared receiver and channel decoding circuit are constituted by the PH302 and CX20106. PH302 is the infrared receiver; CX20106 is a signal processing circuit. Two-channel switch control circuit is composed of bistable electronic switch. short-pulse control of the switching circuit is composedofanalog switch S2, F3 gate and RC components. The S4, F6 and its surrounding components form the long-pulse control switch circuit.
