I was wondering if anyone would happen to know what type of switch this keyboard uses. I know they made several versions but I think this is the original judging from the early Compaq logo and the lack of any II or III on the model name which simply says Enhanced Keyboard. I don't have it in my possession or I would check myself, and this picture is one I found online. I couldn't find much info at all about it.

Edit: Well wouldn't you know, I
would stumble across a page about it after posting this. Apparently it uses a rubber cup and a capacitive switch, something I haven't seen before. Has anyone used one, how does it feel? I'm guessing it is sort of like typing on a regular rubber dome keyboard.
