Looking for micro NO SPST push button switches

Wed Feb 28, 2018 3:16 am

My Pi project calls for about 6 normally open, momentary contact push button switches for the purpose of replacing the mouse (4 directional buttons, two 'mouse buttons', left click / right click)
I do not want tactile buttons, these are too clicky, I require something with a smooth travel and minimal noise.

Now, Ebay and other marketplaces stock 24mm "arcade pushbuttons" that would be ideal, if they weren't so huge.
I'm after something closer to 6mm - 8mm and preferably not too deep, but I cannot find anything, not even manufacturers.
Illumination would be a nice feature, but only if its very dull, since the buttons will sit flush with the touchscreen.

Could anybody offer suggestions or alternatives? I would really like to avoid tactiles if I can.

Here is a rough isketch to demonstrate my use/needs:

have you considered sticky back membrane buttons, a very cheap and easy way to make a good clean job of adding buttons, all you need to cut is a slot to feed the ribbon cable thru the case,

Hmm, I suppose those may work. Now that you mention them, I do remember making electronic "switches" from paper, stickytape and graphene or lead (graphite) pencils when I was a kid. (of course, modern 'lead pencils' contain no lead)


I'd still prefer actual pushbuttons if possible, but at least the suggestion is nicer than tactile switches, thank you.
