If you only want one, then i've got a PIAA switch you can have (left over from adding lights to mine). Got one fitted to mine and it's good quality with a dual illuminated function (green for standby and red for active). Harness and connectors with it which is long enough to reach back to the fusebox (if required). Only thing with it, is that it doesn't have a 'mounting' as such. It's supplied with velcro. Have used this with the one i've fitted and so far it seems fine. If you're interested, just let me know. It's free to a good home. I've no use for it, but it was too 'good' to throw away.
