avoiding using relays??

When I first read the link I thought cool, someone is going to wire all of the high current stuff up through some Triacs .

"Solid state switching" sounds so damned appealing. I haven't kept up, but I don't know of ANY solid state switching device that does not have some voltage drop, something you pretty much cannot afford on 12-14V devices.

I did find these............so evidently I am a little behind..........

PROOF YOU CANNOT BELIEVE AMAZON:

Amazon claims this is a solid state relay, but 30 seconds with Google says "nada."

Only thing better (expensive) is some type of hermetically sealed relays. I'm not talking about relays that are in some plastic cover, I'm talking about actual sealed relays. I used to have a "bucket" of these WWII surplus---and every single one was either high resistance or 24VDC coils.

And then there are vacuum relays..............but they are generally high voltage, low current contacts
