Looking For A 12v Button That Will Close The Circuit For X Seconds
I put in my new SeaEra electric head which I think is just terrific. But my wife and child, god bless their souls, will never hold in the button as long as I'd like them to.
So, I'd like a button that when pressed will keep the circuit closed for 5-10 seconds. Something programmable maybe.

Re: looking for a 12v button that will close the circuit for x seconds
The Square D pneumatic timers are very expensive. You'd probably be better off getting an 8 pin electronic timer and a push button. The button will close the contacts for whatever time you need. Something like this can be found a lot cheaper:
NEW OMRON Timer H3CR-A H3CRA (AC24-48V/DC12-48V) | eBay
You can get them in any voltage. 12 VDC, 120VAC 24VDC, etc. It would be a very easy circuit to draw up. Holler if you need help. ---Gunny---

Push to exit buttons for electric access control mag locks have adjustable time delay. You would probably need a relay as they are usually rated at about 1amp. Some have nc/ no option.

How about one of the small rotary mechanical/relay timers used for hot tubs.
Leviton and Eagle IIRC, are 2 makers.

I read a posting on the Amel Owner's Group from an Amel owner who installed a pneumatic light switch like this one: ELKAY ENERGY SENSE COLUMBUS TIMER 400A PNEUMATIC TIME DELAY SWITCH | eBay
Oh, I know what you mean...out of sight...out of mind...BUT...a few years later, replacing all of the hoses.

Thanks for the all the answers guys, I'll check with Raritan since it will probably be the cheapest and easiest option.

Grainger and McMaster-Carr sell time switches.

Re: looking for a 12v button that will close the circuit for x seconds
Grainger used to sell time delay relays. Simple little things that did what you're asking. The hard part is figuring which contacts to attach to for what you want to do!

The Velleman relay contacts above are limited to 5a DC
That's the problem with most small contactors... The Raritan model handles 20a which is about right for a 10 amp flushing motor moving solids <grin>
