Works great
The switch was easy to install. I would like a bit more grip between my console and the switch because the body of the switch can turn inside the console. I will add my own gasket to fix.

Wish I knew it was momentary in position 3 with a spring return to position 2.
Item is nice, decent quality and arrived quickly I thought. It's a momentary switch in position 3, similar to a automotive application. I might have missed it but I thought it would hold on position 3 and not spring back. I'll be able to make it work, just a little different wiring.
