If you can post a pic that might help. Often times mfg and part number is molded on the switch casing. There are a few places that specialize in obsoletes
Any Quicksilver MX-190 owners here?
Need a favor from a current owner of an MX-190. Specifically, I need to know the manufacturer of the original power switch. I've already contacted Mike Sanders, and he doesn't remember. It's a three position switch that difficult to source new, hence the request. Thanks.
