The model rail manufacturer Märklin produces the turnout mechanism (or points) type 74490 for C track, the 7549 for K track (H0 gauge) and also the 5625 (1 gauge) all fitted with limit switches. The circuit here shows a control box to interface to these mechanisms and also display the status of the turnout using LEDs.
