DC12V Relay Compact Bistable Switch Best Trigger Module For Projects

Feature: \n 1. This is a typical bistable circuit board, press trigger switch to energize relay and press again to dis-energize relay\n2. Designed with screw terminals, it is convenient to wire and easy to use\n3. Trigger switch connect to trigger signal, trigger signal is low lever effective\n4. 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\n5. The power supply should be DC12V, but cannot be used for cars because voltage of cars may exceed 12V \n\nSpecification: \n\nFeatures: \n\n--\n\nThis is a typical bistable circuit board, press trigger switch to energize relay and press again to dis-energize relay. \n\n--\n\nDesigned with screw terminals, it is convenient to wire and easy to use. \n\n--\n\nTrigger switch connect to trigger signal, trigger signal is low lever effective. \n\n--\n\nIf used for conditions of strong interface, it is suggested to connect a diode to input te:
