Parts to Create a Model Railroad Turnout Motor (Switch Machine) Using an SG90 Servo.
Includes a bracket for mounting the servo and a plate to mount one or two SPDT microswitches for power routing or indicator applications.
Two versions (L and R) are possible depending on which microswitch plate is used; not important in most cases, but I had a couple of really tight fits where the opposite hand unit made a difference!
A short video of the finished device in action is included in the ZIP f
