This is a bistable (self-locking) relay module,Trigger once, the relay pull (and holds);Trigger again, the relay releases (and holds)
 
Module interface:
1. 5V: positive power supply (VCC)
2. G:  negative power supply (GND)
3. T1  : Trigger port 1
4. T2  : Trigger port 2
5. T3  : Trigger port 3
6. T4  : Trigger port 4
 
Relay outputs:
1. NO: normally open relay interface
2. COM: Common Interface Relays
3. NC: normally closed relay interface

USE 1:
By default, the relay is release, press the trigger button, the relay pull, press again, the relay release, the third press, the relay pull, and so on.

USE 2:
By default, the relay is release, MCU output low-pulse(0.3-1seconds), the relay pull, low-pulse again, the relay release, the  third low-pulse, the relay pull, and so on.
 
Typical applications:
 
Automotive electronics
Motor
LED
Smart Home
Emergency lighting
MCU development board
Toy car
