Atlas 70000049 Switch Accessory Module for All Scales

Simplify complex track wiring with this versatile all-scales electronic module from Atlas. Designed for N, HO, and O layouts, it supports reverse-loop wiring, power routing, frog wiring, and both twin-coil and stall-motor switch machines, while also providing convenient outputs for panel lighting. The module can directly connect to two Atlas signals for configurable turnout indication on both sides of a switch, making it especially useful for detailed signaling and control installations. For O gauge operators, it also provides an effective solution for wiring 3-rail double crossovers.
