servo motor for model railroad turnout

thingiverse

This is a remix in order to use small (13x6x6mm) micro switches for frog polarization.Furthermore, I added long-holes in order to adjust the micro switches.The appropriate micro switches can be obtained from aliexpress, each approx. $0,10.Please note that these micro switches only switch up to 1A: in case you encounter a short circuit at the very moment your train passes your turnout, they may get damaged.So please make sure your trackwork is fine. You can use only one micro switch (3C) to change the frog's polarity , ore use two of them in order to enable the two rails independently, according to your needs.Printer settings are default, most printers will do this job perfectly.Use M2x10mm screws and nuts or use the screws provided with your servo (if there are any..)
