2-way controller circuit diagram with distinct switch
The four remote switching circuit is shown as above. It uses ZS-01F memory self-locking type bistable relay, so the remote control receiver circuit in the circuit output pulse signal will open the related control functions. However, the circuit also exists such a problem: As the control circuit's on and offbuttons usesthe same remote transmitter button, sometimes due to the phenomenon of false positives caused by misuse, this circuit is not allowed for some accused appear. This control circuit will switch to another relay in the relay, the remote control transmitter. Respectively, it uses two different keys to control the circuit on and off, so opening and closing control is clear, you can avoid the misuse phenomenon. (View)
