Headphone/Speaker Jack Question

Can someone point me in the right direction please?  I want to add a headphone jack to one of the old tyme radios I've hopped up, but I want the speakers to mute when the headphones are used.  Is this done with a wiring trick or is it software controlled?  I hope it's the former!  I have looked all over teh webs but everything I find is related to a laptop or Windows, I can't find anything about wiring them to do this!  Halp me please!!!

IIRC it's a physical 'switch' (like a metal tag) built into the jack that toggles between speakers and phones when plug is inserted/removed. Maybe it's a sw thing now.

It's called a dual circuit or switched socket. You want a headphone jack socket with 5 external pins. One is common for ground, two are L/R audio input, and two are L/R audio output (to speakers).

When you insert the headphone jack the internal pins move, disconnecting from the speaker pins and connecting to the headphones instead.

See diagram D here:


This, I think, is what you need (although the page doesn't actually state it and there's no data sheet, so proceed with caution)

I thought electrocuted meant being killed by electricity?

I was able to find a couple headphone jacks, now I'm starting to rebuild my old tyme radio.  I've decided to try to put an LCD screen in it to display track info and possibly weather & temperature.  And a couple other geek touches.  Currently trying to find code to drive the LCD and get the wiring correct for it.  Then I will attempt to mount it in the housing.

Me too, but just as "literally" can now officially literally mean "not literally", common abusage means it now officially means "got an electric shock". Language is moving on, get with the times!
