I have purchased a new SPDT push/pull switch for my running lights, which consist simply of a single red/green bow light and a 360 degree pole light on the stern. The problem is there is no diagram that comes with this new switch, not even a diagram identifying the four connection points on the switch itself. I have searched online and found no help with a wiring diagram that might help. Even after using a meter on the contacts, I cannot find a solution that works. I simply want the off/on/on sequence to work as it should (off: anchor light on while bow light is off; anchor light on while bow light is on). Can someone help me with this issue?
