13 VDC switch

Looking for a ready made 13VDC electronic switch, that switches a
circuit on when voltage reaches 13+VDC - or a simple circuit. It would
be for optional devices I want to go on when the engine is charging and
off when not charging. Any sources? Not sure what to Google for.

Trivial to design and build.

Since its so trivial for you, how about a basic indication of the
components hookup or reference to the circuit elsewhere?

Anybody (else) know of a finished product source of this trivial
product? Kit?

Nope.

That's mostly a roll yer own.

Sounds like a relay circuit to me.

Off the shelf automotive supplies?
Wally World?

This is starting to smell very much like the upcoming November Kitplanes
column.

You mean I started a new idea? It sure would be handy to plug in
portable devices into the cigarette lighter socket source and not drain
the battery with engine off. OR in case of charging system failure
some non-crucial devices could be turned off automatically. We need
this before November.

Look up zener diode for starters.

Hi abripl,

You'll find what you're looking for there :
