We can design/produce 3 different functional wireless remote control system

individually or design all the 3 functions together.One is self lock model,another

is no lock model,the third is commutative lock model.

Explanation:
1):Self lock model:
[For example 4ch wireless switch]
Press remoter button A first time,the receiver relay is ON,press remoter button A second

time,the receiver relay is OFF,the same as B/C/D. Extend function:When Jumper is OFF

possition, when press button A on the transmitter, receiver channel A goes on 2 seconds

then goes off automaticaly...Same of channel B/C/D.

Use field: Electric equipment ON/OFF wireless control;garage door open/close,light ON/OFF

2):None lock model:

[For example 4ch wireless switch]
Press remoter button A always,the receiver relay is ON,release button A,the receiver relay

is OFF,the same as B/C/D.  
Use field: Electric motor rotation positive and negative wireless control
     
3):Commutative lock model:
[For example 4ch wireless switch]
Press remote button A,the receiver relay A is ON,the relay B/C/D is OFF;
Press remote button B,the receiver relay B is ON,the relay A/C/D is OFF;
Press remote button C,the receiver relay C is ON,the relay A/B/D is OFF;
Press remote button D,the receiver relay D is ON,the relay A/B/C is OFF;
Use field: Electric fan wind speed wireless control
