So I accidentally purchased a 4 pin dpst switch instead of a 3 pin spst. I know the pins on the spst are L, N, and GRD. I was just wondering if someone would tell me what each pin on the dpst is. The 2 top pins are slightly closer to each other and has a small plastic wall in between and the 2 bottom pins have 2 small wires attached going into the rocker. Could someone tell exactly which pins I would use as L, N, and GRD?
