Self-locking, stable, DC 5V, durable relay for smart home LED emergency lighting

Features:

1. This product is a 4-channel toggle latching relay and a low-pulse trigger module.
2. It is a bistable (self-locking) relay module; trigger once, the relay pulls (and holds); trigger again, the relay releases (and holds).
3. USAGE 1: By default, the relay is released; press the trigger button, the relay is pulled; press again, the relay is released; a third press pulls the relay, and so on.
4. USAGE 2: By default, the relay is released; the MCU outputs a low pulse (0.3 to 1 second); the relay is pulled; another low pulse triggers the relay; a third low pulse triggers the relay; the relay is pulled, and so on.
5. Typical applications: automotive electronics, motors, LEDs, smart homes, emergency lighting, MCU development boards, toy cars.

Features:
This product is a 4-channel toggle latching relay and low-pulse trigger module.
It is a bistable (self-locking) relay module. Trigger once, the relay pulls (and holds); trigger again, the relay releases (and holds).
OPERATION 1: By default, the relay is released; press the trigger button, the relay pulls; press again, the relay releases; a third press, the relay pulls, and so on.
USE 2: By default, the relay is released, the MCU output emits a weak pulse (0.3 to 1 second), the relay is energized, another weak pulse is emitted, the relay is released, a third weak pulse is emitted, the relay is energized, and so on.
Typical applications: automotive electronics, motors, LEDs, smart homes, emergency lighting, MCU development boards, toy cars.
The adoption of high-quality electronic components and a precision manufacturing process ensures durability.
