These are e-z n/s HO turnouts and when I got them, they had no method of hooking the green wire(3) up. I have discovered that the left will respond to ac voltage on center + one outer, it remains where it is turned. The Right turnout appears to be spring loaded as it returns to straight line when power is removed. Is a replacement 'switch' available? Is it correct that one returns and the other stays ?? Are there TWO  different type switches??       I used the term"switch" meaning the "push button or slide button" which transfers the current to the right or left wire. These do have factory installed 3 green wire and plug and yes they do have a place next to the track to slide to change direction. The ORIGINAL box said 'remote' switches. these were second hand with no directions or buttons.    Thanks,  James Shelby
