Push button "cover" for tactile switch

Last crawled date: 4 years, 3 months ago

For an electronics project I was needing a nice and striking push button. THe button would have to be mounted in an enclosure and I needed different colour of the button/ rocker face.
So I designed a button, that works in combination with a bargain tactile switch mounted to a PCB.
Please, see for the use case drawing ()PDF file) attached in the things file section.
Using an ordinary 6x6mm tactile switch with a total hight of 7mm and 2.5Nm tactile force will work properly, when the PCB is having an offset of about 23mm measured from the outer surface of an enclousre.
The drill hole needs to be 19mm in diameter and having a small notch of about 2mm for unidirectional orientation of the button's base part.
A damper sprint will compensate for any travel distance greater than the tactile switch would allow for (usually, they are in the range of 1/4mm).
It is recommended to build a 3D model of enclosure, push button and electronics assembly to check for proper fit.
You will find a 3D model of a tactile switch in the thing files, too.
