Excellent quality relay for easy wiring of reversing loops on Marklin model railroads. These are not cheap BUT they take all the guesswork out of wiring reversing loops. In tandem with the control tracks that detect passing trains, you can also quickly and easily AUTOMATE your reversing loop to switch polarity automatically. Wire it up per the Marklin diagram and you're good to go, no worries about short circuits or anything..
