Slits says,
My suggestion is to use a "known good" used one. There are two ... Early is 10 pin Later is 11 pin Which do you need? |

How can you test a used switch before you install?

Mine fissed out when the dimmer went south so got a spare from a vendor on here and got later one (11pin),bridged out the dimmer cause running LED strips in my gauges ...don't need no shi#ty dimmer,my old switch had other issues too so worth doing.
