【screw terminals】 Designed with screw terminals, convenient to wire and easy to use. With built-in protection mechanism, the Single Channel Bistable Control Relay Module ensures the safety of the devices connected to it, reducing the potential risks of electrical faults and malfunctions.
【bistable】 This relay is a bistable circuit board, press trigger switch to energize relay and press again to dis-energize relay.
【trigger switch】 Trigger switch connect to trigger , trigger is low lever effective. The device can be widely applied to varieties of fields such as computer peripherals, machine power switches, charging brace, PLC/test instrument control switch and so on.
【DC 12V】 The power supply should be DC12V, but cannot be used for cars because instant voltage of cars may exceed 12V.ay exceed 12V
【expand application】 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.
