About

This servo mount will allow you to switch a construction brick train turnout using an arduino or other hobbyist microcontrollers with a small servo.

This design has been based around the "SG90 Micro Servo 9g" which is widely avaliable from a wide range of retailers.

Note that there is a 'left' and 'right' version of the base to be used accordingly with left and right hand switches.

Assembly

"servoHousingV4Holder" Holds the servo itself, slide the servo into the holder. This is then placed on top of "servoHousingBase". "servoHousingSwitch" is then fitted on the end of the servo's arm to reduce strain on the servo. Clip the whole lot onto the top of your train switch, keeping the yellow lever attached and positioned in the middle of the "V" shaped part of the servo housing switch part, then add the "servoHousingLid" to finish it all off.

Example Implementation

Change Log

Version 2 (19th January 2017)

The switch piece has been updated and now has a small hole for the screw supplied with the servo. See servoHousingV2Switch.stl servo

HousingV1Switch.stl is still avaliable if you would still like it without the hole.
