The wireless remote control switch circuit is composed of the wireless remote control transmitter and receiver wireless remote control circuit. The radio remote control transmitter circuit is composed of the pulse encoder circuit and radio transmitter circuit. It is shown as above. Components selectionR1 ~ R20 uses 1/4W carbon film resistors or metal film resistors; R21 chooses 1/2W metal film resistors. C1 and C4 use high-frequency ceramic capacitors; C2 and C6 use monolithic capacitors; C3 and C7, C8 use electrolytic capacitors voltage 16V; C5 uses voltage 400V CBB capacitors. VD1 ~ VD13 and VD16 ~ VD20 use 1N4148 silicon switch diode; VD14 and VD15 use 1N4007 type silicon rectifier diodes.VS uses 1W, 6.2V silicon voltage regulator diodes. V1 ~ V6 use S9013 or C8050, S8050, 3DG9013, 3DG8050 silicon NPN transistor. VT1 ~ VT5 use TLC336A (3A, 600V) type bidirectional thyristor. IC1, IC5 and IC7 use CC4017 or CD4017 type decimal counting / pulse divider circuits; IC2 and IC6 use CC4011 or CD4011 type four NAND gate integrated circuit ; IC3 uses T630 type radio transmitter IC; IC4 uses T631 type radio receiver integrated circuit.S1 ~ S8 use tiny moving together (normally open) button. GB uses two 5 batteries.
