Keyboard question/advise needed

[phungi]

I am trying to "modify" a computer keyboard (PC) to add external jacks that will allow me to close a switch with a key-press.

I purchased two different keyboards and then got one from our IT guys (at a University) but all three have a thin plastic membrane with a circuit board embedded. I need an old-fashioned keyboard with actual buttons that close a switch when pressed.

Hmmm, could you maybe replace the contacts of a little-used button ("insert" or "scroll lock" or something) with a minature push button from RS or Maplin, and stick the original button to the top of the new switch?

Or, you could find a panel-mount pushbutton with a shallow back end and mount it in a space on the keyboard...

I know neither answer is ideal, but it's just my thoughts...
If you want me to find a suitable push button from RS, give me a shout.
