Universal Key Switch Mount Holder
thingiverse
This is a simple snap fit base designed specifically for the widely used Chinese universal 4 wire ignition switch. I attach it to a 40mm tube using two zip ties, which supports widths of less than 5.5mm. FreeCAD source code is included, so feel free to remix and modify it if you can! To get the compatible Key Switch, visit https://www.ebay.com/itm/182381934797 for an example. On September 16, 2019, I added another derived version that fits on both 25mm and/or 20mm square tubing.
