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.
