2 way switching using hall effect sensor

KC868-H32B's input port is for sensor trigger use, if you really want to see the lamp state , you can use KC868-COL connect with your sensor to see the feedback state. (make sure your hall effect sensor output signal type is dry contact [just means output OPEN/CLOSE] ).
