You can control the actuator externally with pushbuttons or switches. The actuator automatically detects what is connected and adjusts the function accordingly.
If a pushbutton is connected, the actuator switches on when it is pressed once and switches off again when it is pressed again.
If a switch is connected, the actuator switches on the first time it is pressed and switches off again when it is pressed again. The actuator can also be switched on and off in between by radio, no matter what the switch position is.
This means that it can also be used with alternating or cross circuits. The switch actuator is always connected to the lamp wire.
