The following is a wiring mode with a lock switch

Take 16MM five foot buttons as an example, the 2 one is connected with lights, the other 3 are normally open, normally closed and common points

2, the middle three C1 pin input common. Nc1 is normally closed. N01 is often developed. The button can be freely selected for opening or closing

Because the light and the control are independent, there are two ways to connect them:

1.The lamp can be connected to the normally bright, +, - connected to the positive and negative pole of the 12V power supply. Control can choose C, NO or C, NC. No matter the switch is on and off, the lights are bright.
