My guess is the switch has LED indicators the positive and negative terminals are for power to the led indicators. Look for the manufacturer doc on the switch it will detail this info, places like digikey.com probably have the info you need
Got 5 latching switches as per attached picture BM-16, 12VDC. The 3 center terminals are marked C, NO, NC, the other 2 has a + mark and the other has a - mark.
I will use them as ON/OFF so the power will go between the C and NC terminals but how do I wire to have the light ON when the switch is ON?
Thanks
