Working voltage: DC 6-24V Working current: 60-70mA Standby current: 1uA Load current: AC 250V/10A, DC 30V/10A Trigger mode: Low pulse trigger This is a bistable (self-locking) relay module. Trigger once, the relay pulls and holds; trigger again, the relay releases and holds. Module interface: 1. VCC: Positive power supply (VCC) 2. GND: Negative power supply (GND) 3. T: Low pulse trigger Relay outputs: 1. NO: Normally open relay interface 2. COM: Common relay interface 3. NC: Normally closed relay interface Usage: By default, the relay is released. Press the trigger button, the relay pulls in; press again, the relay releases; press a third time, the relay pulls in again, and so on. Typical applications: - MCU development board - Automotive electronics - Industrial equipment - Emergency lighting - Smart home - Toy car - Motor - LED Size: 4.8 x 1.1 cm / 1.89 x 0.43 inch Color: As shown Material: PC + Metal Package Contents: 5 x 6-24V Flip-Flop Latch Relay Note: Light and different displays may cause the color of the item in the picture to vary slightly from the real thing. The measurement allowed error is +/- 1-3 cm.
