Real-Switch Relay Controls

Sometimes you just need to turn something on and off.

Control lights, accessories, uncouplers, signals, motors, AC circuits. Anywhere you’d use an on/off switch.


Relays are real switches. They’re fully isolated which makes them ideal to control track power, high voltage or high current circuits, lighting, and signals.

Our Real-Switch Relay Bases come with two or four relay switches, each with 10 amp rated contacts, and a place to plug in a Touch Toggle to control each relay.

All of our relays have “double throw” action, meaning that contacts connect to one circuit when the relay is powered, and another when it is not; You will usually only need to use one side contact or the other. Each set of contacts have large screw-tight terminal blocks that are removable for easy wiring. These terminals accept 14-22 gauge wires to connect to each set of “SPDT” relay contacts. Adjacent relays can be linked with an Input Splitter to create a 2 or more pole switch.

Our Real-Switch Relay Bases use a plug-in 12v power supply. Our 12v Bases can be daisy-chained when mounted side-by-side with Relay or other 12v bases. This way power can be shared with up to 16 Touch Toggle controlled relays in a row, all by a single power supply.

Handy red LEDs light up to indicate when a toggle is red and its relay coil is powered. Our relays have a 100% duty cycle, which means they can remain on indefinitely.
