Design for Gikfun 12mmx12mm pushbutton wall pass-through
Posted: Wed Nov 24, 2021 6:15 pm
Hello friends,
I'm designing and building a custom alarm clock for my son. Arduino inside, with a speaker and DS3231 timing chip with battery backup.
I need buttons on the outside to set time, alarm, etc. I'm using these buttons, which will be along the side of the case.
So I need a way to place the body on the inside, but have the hat stick through the case - and there needs to be a 'backboard' so that when you press the button, it stays in place and registers a press, rather than just sliding into the case.
The trick is, there are some protrusions on the top of the body, so there needs to be a recess in the wall, so you can place the button against it, then slide it down into place.
After a few iterations, I came up with this design.
View from the inside - showing the 'backstop' as well as the pockets that let the button slide down into place: From the outside, we need a recess for the button, as well as some room for the hat to 'snap on' to the button switch itself: Tried it last night, and works like a charm. Here are some tech drawings I made in case anyone wants to use in their designs: I'm a fairly new maker, very new to FreeCAD, grateful for all constructive critique / suggestions.
[EDIT]: Uploading model: Best,
