Review on WirthCo (20188) Battery Disconnect by Charles Quinones

I needed a knife switch of the lowest possible impedance for a radio project, which made this Wirthco product an easy choice. Every other knife switch I've seen has been a cheesy little job made of much lighter CHROME PLATED metal. Chrome looks nice, true, but for conducting electricity I'll take nice beefy sections of copper and brass over chromed-up mystery metal any day. That's what the Wirthco's got. I've used Wirthco switches for the intended automotive applications as well, and they've always worked flawlessly. They can pass LOTS of current. You pretty much have to handle one to appreciate what a serious hunk of electrical infrastructure it is.
