Summary

This is an update to my Paddle Switch Mount. See that project for more information. It is now a one-piece design that allows use of a switch boot for better ingress protection. Though note that the rubber switch boot will probably wear out with enough use.

This should work with most any electronic shifting system where you can add extra buttons, but you will need to source the appropriate connector. It can also be put to use for other electronic switching purposes: a horn or lights, ebike display control, ejection seat, etc.

I have uploaded two variations on the part: one designed for a 28mm diameter to fit over a handlebar with bar tape on it, and another for a 23.8mm diameter to fit on a bare road bike handlebar. For flat bars, like mountain bikes or cruisers, modify the Fusion 360 file and change the BarPlusTapeDia user parameter to something more like 22.2mm or 31.8mm (plus a bit if using some rubber strip/innertube for grip), depending on the mounting location.
