I once thought about integrating an SMD push button directly onto the PCB.
What do you think?

Hi Hartmut,
does any part of the metal shell like the small tabs that fix this shell reach down to the PCB? If yes you better keep the space underneath the switch free from traces...

With best regards,
Torsten

Hi Torsten,

no the tabs are inside the plastic body and are not on the board. I'm still waiting for the delivery and want to remove the metal case

Hi Hartmut,

I believe on the switches in your picture, the metal casing does contact the board underneath, where the sides are folded inwards. If they are the type I'm thinking of, the case can't be removed as the switch mechanism would fall out. However, a strategically placed piece of electrical tape on the board before mounting the switch would be enough to prevent any shorts.

Personally I use through-hole buttons on the PCB so that I can remote them if I want to. Not so easy to remote a SMD button, plus I'm not sure how someone would access the button on a running clock.
