DC 12V 1 Channel Bistable Circuit Board Trigger Switch Relay Control Module HigQ
- The power supply should be DC12V, but cannot be used for cars because instant voltage of cars may exceed 12V
- This is a typical bistable circuit board, press trigger switch to energize relay and press again to dis-energize relay
- Trigger switch connect to trigger signal, trigger signal is low lever effective
- If used for conditions of strong interface, it is suggested to connect a diode to input terminal in series, and connect a 470UF capacitor to GND in parallel
- Designed with screw terminals, it is convenient to wire and easy to use
