Here is the manufacturer. I bought mine from Finishline, but if this one looks the same and illuminates (mine does not) I would prefer this one. The on from Finishline you will have to solder the connectors, but if you click on the next page in the link, the terminal end looks much heavier. Illuminating button would be great.
