Summary

I've been wanting to design a way to replace the latching push button (Switch SE) on the Radiomaster Boxer Radio. I saw Limon's mini-review and it encouraged me to tear the radio a part and get to work. The shape of the button isn't very difficult to model and it didn't take long to get a mock up that fit. I pulled a toggle switch from USB RC controller, but any mini 2 position with a 6mm diameter mounting size.

You do obviously need to open the radio and remove the main board. The push button is directly soldered to the main board so you need to use a hot air station or some side cutters to remove it. I cleaned it up with some Isopropyl Alcohol.

I printed the insert out of Sainsmart TPU so it fits snugly. The print is tight enough that I didn't use the toggle switch mounting nut. The print fits into the slots that the original button used to guide it up and down. Install wires and carefully put the radio back together.
