How To Install Servos the Quick and Easy Way

We will be on vacation from July 29 through Aug 8.  The web site will be open but shipping will not occur until we return.  Thank you for your patience!

SwitchWright Upside-Down Servo Drive

In this installation method, the servo drives the throw bar through a hole in the subroadbed.  The turnout is upside-down and goes through a fulcrum. The spring of the wire makes an over-the-center spring that helps keep the points against the stock rail. This allows the servo to be turned off.

Diagram of another way to acheive the Switch Wright geometry turning the servo 90 degrees. You can use our brackets or make your own.

Using a crank to drive the throwbar
This is the way to retro-fit existing turnouts.  A small hole is drilled between the ties about 3/8" away from the tie bar and a 1/16" tube inserted.  A piece of .020" spring wire is then bent and put in the hole to make a crank.  With the switch points blocked in the center o the throw, the servo is attached to the bottom of the subroadbed.
