Colour light signals (updated) hello friends, I recently embarked on a new project for my N scale layout, installing and operating colour light signals. I bought all my components from "patronics", specialists in colour light signals. The switch that the company suggested that i should use with their signals was the DPDT (double pole, double throw)switch. As soon as the switch's arrived i was confused, there were six connections on the bottom of each switch. I read throagh all books i had on hand remotely involved with electronics looking for a plan or diagram explaining how the DPDT switch worked but to no result! I would be most gratefull if anyone has any plans or diagrams showing how to wire up a DPDT switch or can help in any way with my project. NICK C Ps. thankyou for all your helpful advice and help on wiring up the DPDT switch, however i have just remembered that my 2 aspect colour light signals only have 2 wires!, does this complicate the wiring to the switch?, if it does could you please help me by explaining a possible wiring plan?
