A quick bit of googling suggests that ‘Tactile Switches’ are what’s needed…..I’ve used these before on other projects,
I went though a few choices (and hours) before finding a seemingly ideal switch (more later)
The types of tactile switch I’ve used in the past were usually a bit wobbly – especially the longer ones. I’ve found that the top will wiggle about when pressing the button, some were a mm or so…I don’t think any keyboard would feel good typing on those – I’ll use these as a last resort if nothing else rolls up.
The Shorter ones could be a go, a lot less wobble, but there’s going to be a bit of trickery needed to mount the buttons onto them – that’s fine, I have a 3D Printer and ain’t afraid to use it
After much scrolling through google images, ebay I found this type below – Has an ‘insert’ for the buttons AND is available in < 8.8mm square size……..and it’s cheap………BUT, it’s still that wobbly type of setup. I’d need to do something to restrict it (like this bloke did – Hackaday Link)
After a couple of days procrastinating and occasionally googling for better ideas, I found what I think may be the perfect switch! My favourite website Aliexpress to the rescue here!
Looks Perfect – Small, Lots of legs, so will be stable.
I Splashed out £5.45 and purchased 120 switches……..90 of the non locking types and another 30 of the locking types (for the Shift Lock Key!)
Now to wait for the slowboat!
