Sorry the part number I listed earlier was the RS Components number, what I did the google search on was the Optek part number OPB917B

Also I have used the OPB916B its slightly shorter reach which may suit better.

well thanks for checking but Digikey and Allied both have minimum orders in the 100's because they do not stock them. Man this if frustrating work.

alright I found them at Newark.com
they charge a riidiculouse $15 handling fee to ship them direct from the UK but I went for it any way.
Hood, How do you have yours wired to the PC?
Im using bob campbells breakout board so I was just curiouse how the wiring would go on this switch.

I just have it connected via my breakout (pmdx 122)
The Cathode and Ground (Black and Green) are connected together and taken to a ground on the breakout.
The Output (blue)  goes to the Input you choose on your breakout.
The Vcc (white)  is connected directly to a 5V supply from the breakout.
The Anode (red) is also connected to the 5V but has a 220 ohm resistor in line.

All thats left to do is configure the Index in Mach for the pin you connected to and you should be up and running.
I would advise to use shielded wire.
