The switch was actually made by Nicky. I rewired the electrical wiring using a non-relay Gator hydraulic shield and used heavier gauge wire (8 gauge) and it works like new again. The switch definitely handles a good amount of power! The project has been greatly simplified!
very good quality switch reminds me of something in the cockpit of an old plane. Works perfectly. UPDATE July 19, 2020: No longer works (tested). Ordered on 07/05/2019. As an exhaust switch it has lasted just over a year. One star discount.
Don't worry it took 3 months. Used as a jack switch on a flatboat, it was dry mounted to my console so moisture was not an issue. The boat is also stored in the garage when not in use. I don't know how much better I could have taken care of the switch.
