Review on Jtron Automotive Relay Harness Set: 12V 40A 4-Pin SPDT With Interlocking Relay Socket For LED Light Bar Wiring Harness Kit And Push Button Switch by Jason Ingram

Switch works great, but the wiring setup for it is non-intuitive. You have to power the switch to it can power he light. Not one to read manuals on what I though would be pretty straight-forward switch install, I had to pull it and redo the wiring. I have in on the interior of a boat, I kind of question whether it would be salt-water resistance. I don't see any attempt to seal it, and salt water is pretty hard on electronics.
