Want to use a longer hook up to my RealTrax Operating Track section. Switch in stock control looks like a double pole, double through with momentary (on)-off-(on). However I can not for the life of me figure out with my meter how it work. Does anyone of you kind souls have a schematic drawing that would help me out? Thanks in advance!!
