Skill level: Simple - similar to installing a stall motor switch machine. For DCC you should understand how to operate accessories with your DCC system.

The singlet has a baby brother, the Micro Singlet. It is a simple servo decoder designed to drive turnouts and only turnouts. It solves the problem of servo buzzing by turning the servo off at the end of the throw. Special circuitry and programming has been built in to accomplish this without a large jerk at restart.
The Micro Singlet works has a fascia controller for controlling the turnout manually. It is the same fascia controller used by my other servo boards. The Micro uses a pushbutton to throw the turnout. If you are in love with toggles you will need the older Singlet (see below) or the SwitchWright.
Installation is simple. It is designed to work with a servo under the table using the geometry of the SwitchWright bracket. This mounting method provides an over the center spring action that keeps the points in place after the servo turns off. After years of trying various methods this method really works the best and avoids the servo buzzing that happens when they are fighting to keep the points in place. Centering for mounting the servo is done by holding down the fascia controller button until the servo drives to the center. A tap on the button releases it.
The video (left) shows the Micro Singlet and a servo mounted on a SwitchWright bracket. It also works very nicely with the Micro Switch machine as pictured above.
