Servos and Accessories

The Micro Switch Machine is a small servo-based switch machine with a built-in snap switch. It is 1.25 inches wide and 1.5 inches tall. It is ideal for N scale installations yet has enough torque to throw O scale turnouts. It comes completely assembled.

Part Number

Miniature Servo
Subminiature 9g servo. These have plenty of power for hinged point turnouts and smaller rail (code 55 and smaller) solid point turnouts - if used with the servo mounting kit (SMK002 below) it can handle higher loads, up to code 100 non-hinged rail. If the point rails are hinged then the rail size is not an issue - it has been used up to G scale. Our servo brackets (see below) are custom made to fit these servos. Size 1.25" wide (including mounting tabs) x 0.5" deep x 1.125" tall. Servo lead about 7". The label on the servo and the lead colors may vary between batches. Works with all of our boards. Every servo is tested before shipping.

Micro Switch Machine w/ Snap Switch
For use with Octo III, , Micro Singlet, Singlet II+, SwitchWright, Quad-PIC, Quad-LN or other RC servo compatible board


The Micro Switch Machine is based on the SG90 servo with a 5 Amp rated snap switch mounted so that it is turned on and off at half throw - ideal for powering frogs. The wire actuator is already mounted for you. The Micro Switch Machine is ready to go. Comes with a piece of double-sided foam tape for ease of mounting as well as two #4x1/2" screws for permanent mounting. The #4 screws fit snugly in the mounting holes so that they will not fall out when you are under the layout :). Use with any of your servo decoders to power a turnout and the contacts provide frog power.

Micro Switch Machine (without Snap Switch)
For use with Octo III, , Micro Singlet, Singlet II+, SwitchWright, Quad-PIC, Quad-LN or other RC servo compatible board


The Micro Switch Machine is based on the SG90 servo. This version does not have the snap switch mounted saving you money if you have another way to power the frog or you don't need powered frogs. The wire actuator is already mounted for you. The Micro Switch Machine is ready to go. Comes with a piece of double-sided foam tape for ease of mounting as well as 3 #4x1/2" screws for permanent mounting. Use with any of your servo decoders to power a turnout.

3D Printed Micro Servo Bracket Kit (servo not included)
This bracket is designed to mount underneath the layout and actuate the points with a spring wire. It is the same bracket as used in our Micro Switch Machine. However you are free to use this bracket in other creative ways if you feel the need to experiment. Comes with a piece of foam tape for easy attachment to the layout and two 1/2" x #4 screws for permanent attachment. A #4 screw fits snugly in the mounting holes so that when you are under the layout the screws will not fall in your face. Also comes with a piece of music wire.

Actuating Wire- .032" steel music wire. Length - 5" before assembly; 3" usable length after assembly (maximum thickness of subroadbed + track height)

Bracket Size - 1 3/16" wide x 1.0" deep X 1 3/16" high

Fits servo size 0,87" (23mm) wide x .47" (12mm) deep (SG90, 9g servos).

Minimum mounting clearance under layout - 1.5"

Mounting Screws - #4 x 1/2" for bracket to layout; 1 screw (comes with servo) for attachment of servo to bracket

SwitchWright Miniature Servo Bracket Kit (servo not included)
The SwitchWright is a bigger and sturdier servo bracket 3D printed to make it rigid. It holds the servo securely with two screws. The kit comes with everything you need - the mount, the wire, mounting screws for the servo and for mounting the bracket to the layout. We also include a piece of double-sided foam tape for holding the bracket in place until you can get the mounting screws in place.

Specs

Actuating Wire- .032" steel music wire. Length - 5" before assembly; 3" usable length after assembly (maximum thickness of subroadbed + track height)

Bracket Size - 1.97" wide x 1.138" deep X 1.0" high

Fascia Mount for Singlet II
Not for Micro Singlet - see Fascia Controller page for Micro

Made of precision 1/8" thick laser-cut acrylic, these mounts can be used to neatly mount your Singlets. Simply use a 1-3/8" hole saw to place on your fascia. The four included screws hold it securely in place and the recess keeps the button safely out of the way of bellies. The dark plastic makes the LEDs stand out. Comes as a kit that includes the 2 pieces and 4 screws. The pieces can be easily glued together with solvent designed for acrylic such as Weldon 3 or epoxy. (MEK and other styrene glues will NOT work). Just put the pieces together and flow a small amount of solvent on with a brush. Can be spray-painted a different color or used as is. Parts are laser cut by Monster Model Works.
Size 1.5" x 1.5" x 1/4" deep (without parts mounted). The singlet will stick out a bit to one side so take this into account when mounting several units together.

Remote DPDT Relay Board
This remote relay plugs in to the breakout daughter board (below) and gives you two circuits for powering frogs, signals and so forth. Board has a 12V, 2A hi-sensitivity relay that draws just 23 mA, relay drive circuitry, and a terminal block for easy wiring. Can also be used without the Quad - red wire, 12V, black wire, ground, white wire, signal (0V = OFF, greater than 1.4V is ON). Comes with a 12" extension cord - extra length can be added with servo extensions.
Does not work with Micro Singlet. For Singlet II only

Remote SPDT 10 A Relay Board
This remote relay plugs in to the breakout daughter board (below) and gives you one high-power circuit for powering frogs, signals and so forth. Board has a 12V, 10A hi-sensitivity relay that draws just 30 mA, relay drive circuitry, and a terminal block for easy wiring. Can also be used without the Quad - red wire, 12V, black wire, ground, white wire, signal (0V = OFF, greater than 1.4V is ON). Comes with a 12" extension cord - extra length can be added with servo extensions.

In-Line Servo Reverser
You can often reverse your servo throw direction by turning it around or reversing the servo linkage. Sometimes there just isn't room under a turnout to do this. You can't reverse the servo direction by swapping wires since servos work by varying the pulse width and reversing the wires will just disconnect off the servo. In cases where you want to reverse the servo rotation direction, this servo reverser comes in handy. If you put this in line with the servo it will swap the two ends about the center. [It works by mirroring the pulse around 1.5 ms which is the center on a servo. I.e. if a 2 ms pulse is input, the reverser will output 1 ms and if a 1 ms pulse is input it will output a 2ms pulse.]

No-Buzz In-Line Servo Quieter
Sometimes a servo will buzz or chatter continuously. Some poeple find this very annoying. The No-Buzz goes in line with the servo cord and quiets the servo. Here is how it works - if the servo is stopped in the same position for more than about a second the circuit turns off the servo. If the servo starts moving again it will turn it on and drive the servo until it stops again. When the servo is stopped the gears will hold most switches in place. If you use the SwitchWright geometry then the wire acts as a over-the-center spring and also holds the points while the servo is off. A side benefit of the No-Buzz is that you do not need to adjust the servo as precisely but can overdrive the position and let the servo relax back after it turns off.
