Looking for: one (1) Apple II keyboard keyswitch

I've been slowly restoring an Apple II (original) to working condition and my last hurdle is getting the keyboard working reliably. When I started a handful of keys didn't work, worked intermittently or had debouncing problems and I managed to get them working fairly well again by carefully working in some contact cleaner into the switch. (It's a real PITA since these things are solid blocks of plastic and cannot be disassembled.) I have one key left that I cannot make work through this method. I'd rather not sacrifice another keyboard just for a single keyswitch; does anyone have any of these going spare or have a "salvage quality" Apple II keyboard I could pull a switch from? (Or does anyone have better repair advice for these switches?) Thanks as always, Josh
