Do you know what this box is?

[Sinc]

This little box has a switch to turn the stereo cockpit speakers on and off.

It also has what appears to be a locking 12v socket and a co-ax socket on the front.

It's clearly a speaker switch - 'cos that's what it does - but I wonder what the purpose of the other socket combination is for.

Googling hasn't turned up a similar box.

Any ideas?

That just looks like a generic electronics enclosure that someone has fitted their own switch and socket to.

The other socket looks like a 12 volt power socket normally used in cars. All you can really do is remove the box and look at the wiring.

Stick a multi meter in it and see if it shows any voltage.

Seen some weird and wonderful things such as pl259's being used for power!

There is 12V at the socket that looks like a 12V socket - no surprise there.

I guess what I'm asking is if anyone has seen a similar box and what it's original purpose was.

Suspect it was used to plug 12v tv into, antenna for tv and switch to turn some powered speakers on?

It's for the extension cable to the 12v DC version of the Snurble Grip-Thribley.

AFAIR only 350 were made, and each one was signed by the initials of the maker, Charles Elliott.

He even made a mirror image for the Australian market, such was his dedication to the art of engineering.

Yes, I’ve seen lots of similar boxes.






They were on the shelf at Maplin . Their purpose was to hold people’s DIY electronics projects.

As several others have already said, this assembly is home-made by a previous owner. There is no manufactured product out there to identify it as.

Matthew’s suggestion of a TV connection point would sound plausible if the small brass connector was an RF type, but it looks to me more like an RCA (“phono”) one - can’t be sure since the picture lacks contrast. Does that connector carry a mono audio feed to the boat’s stereo, and if so, given the speaker switch, might the installation be for a portable sound source like maybe a DAB radio or something?

There's no other obvious use for the other connections - but I'll keep investigating.

Well, the power socket is a power socket, so it's really just the single RCA that needs identifying. Can you not follow its wiring back to wherever it goes?

(EDIT: To be clear, this is a reply to the post it appears above - the forum servers seem to have lost NTP sync or something of that nature.)

Thanks for the thoughts.

It does what I want it to at the moment - switches the stereo speakers on/off in the cockpit.

Pete,

Yes - that's the plan - but easier said than done given where the wiring goes.

(don't know what's happened to the sequence here.)
