Wincal Relay DC 12V Single Channel Module Bistable Switch Circuit Trigger Control

Bistable Circuit Relay: This is a typical bistable circuit board, press trigger switch to energize relay and press again to dis-energize relay Bistable Switch Convenient Wiring: Trigger switch relay is designed with screw terminals, it is convenient to wire and easy to use Single Channel Relay Module Validity: Trigger switch connect to trigger signal, trigger signal is low lever effective Recommendation: 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 DC12V Relay: The power supply should be DC12V, but cannot be used for cars because instant voltage of cars may exceed 12V
