Many controlled circuits need real switching. Relays let our small electronic systems throw real switches for high current, AC, track power, or signaling circuits. Relays let you switch any of these with the safety of total isolation between the control system and the switched terminals.

We created our Relay Base controls to let you power these machines as simply as possible, with just three screw type output terminals that connect to an Single Pole Double Throw (SPDT) switch. Relay Bases come in 2, or 4 output models.
Often inputs to a Relay Base may be linked with inputs to other bases with an Input Splitter. This is handy for adding point contacts to servo, twin-coil, or stall motor operations that might be tricky or impossible otherwise.
Common Uses for Relay Switching
- Control multi amp power to uncoupling ramp magnets. Use our Momentary Touch controls for circuits like these that can’t stay on without overheating.
- Turn on DC or DCC track power to track blocks.
- Use instead of traditional switches to control overhead room or layout lighting up to 10 amps.
- Add to turnout controls to provide frog power or signaling output
- Trigger sound effects or other accessories at trackside using our Toggle Cup mounts for truly local control.
- Operate building lights and effects
Our Relay Bases have a 10 amp output for up to 30v DC or 120v AC, so can handle most switching jobs.
Multiple relay outputs can be controlled by a single input. Use our Input Splitter to connect two inputs with a plug-in adapter. Side by side operation can be used for a DPDT control. For users with soldering gear, make this same connection with a drop of solder on a solder jumper spot.This spot is on the back of the Relay Base just between any two inputs. Only connect one toggle to joined inputs
- Use an Input Splitter to operate two or three outputs together. You can operate a second input on the Relay Base, on a Direct base, Twin-Coil Base, or Servo Base at the same time for signals, frog power, or anything you might think of.
- Use a 3-1 Multi-Input Adapter to control any output from two or three Touch Toggles in different locations. Great for two sided operation on peninsulas and modules. All the attached Toggles show the same indication at all times.
- Use our Toggle Cups to conveniently place single light Touch Toggles in the fascia just below turnouts or controlled accessories. Use these instead of a control panel, or use with a 3-1 Multi-Input Adapter to offer a second alternative local control.
- Use 3-Pin Extension Cables to extend your Toggles 20 feet or more. Plug extensions end to end for longer runs runs.
- Use our 12v DC Power Supply to power your system. All of our 12v Bases have power sharing pins that let each Base plug into the next, so you’ll need only one supply at each Base location).
- Connect your own power supply connections with our DC Input Terminal Adapters.
- Extend your plug in power supply, or start a power buss with our DC Output Terminal Adapters.
Using Relay Bases to operate higher current reversing current motors
Each of these machines can be operated using our Relay Base, and a separate power supply or supplies as shown in the two circuits below.
