"I love it when a plan comes together" (Hannibal Hayes Voice) The dimmer switch lives in a very hostile environment with lots of rain, mud, and salt. It shorts out or open circuits often. GM sent a new invention to the MIT engineering school years ago for their comments, a dimmer switch mounted on the steering column. MIT replied that "All our faculty and most of our students are getting their feet hung up in the steering wheel while trying to dim the lights- - - - -put the switch back on the floor where the Lord intended it to be!"
LOL!
