This system is designed to integrate with your snap bipolar 2 wire switch machines, most notably the

• Kato
• Rokuhan
• Rapido Trains, and
• any others using 2 wire snap machines.

It is available for 2 scales: N and HO Scales and includes 3 Dwarf signals.

A unique feature designed into this system is that it remembers the direction of the turnout from the last time it was used, even when power has been interrupted.

Another unique feature is that it can be used with either AC or DC power, directly from the turnout power!  You can also cascade each controller so that you only need to power one and all are powered.

Finally, if a combination of turnouts is used, such as in a ladder, and each does not need 3 dwarf signals attached, then

1. A mix of these products will provide a less expensive way to signal the ladder (see note below), and

2. The spare fiber spaces on the Controller can be used to connect 2 fibers from the controller to a turnout display board.

The assembly couldn't be simpler:

1. Connect 2 wires from the left hand 2 socket connector on the Dwarvin Snap Controller to the Snap machine switch control unit - no soldering needed.
   
2. Add power to the Dwarvin Snap controller either using a 9V supply (barrel connector) or directly from your AC or DC bus via the 2 socket connector on the right hand side of the unit.
   
3. Finally, insert the Dwarf Signals into the layout where required and insert the fibers into the Snap Controller.
   

The whole kit consists of (there are sub kits as well)

• 3 Dwarf signals with 2 pairs of ~2ft of fiber each

• 1 Turnout Signal Controller unit

• Set of wires

• Optional Power Supply

You can buy any combination of products to suit your needs.

Each N Dwarf signal is: 12mm tall and 3mm wide.

This is especially helpful for operating sessions where it is very useful to see which way the dispatcher has a switch set. 

Here are the instructions for use.
