Walthers Layout Control System brings you a low-cost solution for easy turnout control for HO, N, Z, S, and O Scale layouts with this five-pack of Switch Machines! The Layout Control System is expandable at any time to grow with your layout, and can be used with DCC- or DC-power - and switch machines feature optional DCC operation. The system uses plug-and-play servo-style wiring with connectors, so no soldering is needed; two styles of cables are available separately to expand your wiring as needed. User-friendly instructions are included with all items, and drilling templates for easy mounting on your layout or fascia are included as appropriate. Using combinations of the system components, which include a servo-based slow-motion Switch Machine, Power Distribution Block, LED panel indicator-control pushbutton switches, add-on system cabling, a 2-amp 12V Filtered DC Power Supply and a three-piece drill set, you can easily build a complete control system.
