Hi Bob
The PL0066 looks identical to the switches in late-model Parkers, so I'm guessing it is OK to use this for your guitar.

You can use a multi-meter in audio mode to safely test the signal flows for any switch. By trying the various switch positions you will be able to work out which points are correct to solder. You should get a 'beep' corresponding to the following switch combinations:

Left position: one-side-Only with centre
Centre position: both/either sides with centre
Right position: The other side-only, with centre.

It's really easy to get the pickups soldered around the wrong way, especially if you are working on the guitar face down, although this doesn't affect how the switch works.

It doesn't matter which switch you use as a replacement, as long as you get the test result as above. If you don't have a multi-meter, I highly recommend getting one, they save so much time trying to work out how things work!

I do have a multimeter.

The black is obviously the ground, the red and blue must be the two pickups.

So if I understand, middle position should show continuity between ground and both blue and red

One extreme position should show continuity between ground and blue but not read

The other extreme should show continuity between ground and red but not blue

Yes?

I'll have to take the PL0066 out again and look. Perhaps the switch is defective or I screwed something up.

Thanks again
Bob

Yes that’s how the switches on my guitars work and I would think, the PL0066. I can’t comment on the SPDT switches as I don’t have them. If they work the same then I’d be tempted to get them because the Parker/PL0066 switches are so unreliable.

I think you should able to do the continuity test on your existing switch without removing it, just take out the battery.

If your center connection is ground, then you don't want continuity to either end lug to the center pole in center position .  It should be "off."  Otherwise both signals shunt to ground. 

If your center connection is signal out to jack, then Jamie's on-on-on approach makes sense and you do want continuity between all three lugs in the center position.  (IMHO this approach is more likely to "thump" through the amp when you make/break the switch though.)

You need to properly ID your preamp board and read their setup guide to know for sure.  Compare their recommended wiring scheme against what you have in your guitar.  Also check against your other DF.

I hope I'm not double posting, the browser crashed during my first try. If so, this one might be better anyway as I've had time to reword.

Trying to hold the broken switch together it looks like two switches with a center toggle. I tried glue but it didn't hold well. It just came apart again.

In the center position it looks like R connects to Bk (gnd) and Bl also connects to Bk. The two switches are two leaves of metal that are touching each other, closing the circuit.

Moving the switch in either direction seems to spread the leaves apart, opening one side of the circuit or the other.

Does this make sense? Is the DPDT on/on/on? If not what is it?

The nut appears to be 7/16", the guitar is USA made, would that be correct?

Thanks again - and sorry for being such a pest.

Bob

Posts like this are never pesty! They are the most important posts on this forum!
That description seems like exactly what the switch is supposed to be doing.

Thanks,

So does that describe a DBDT on/on/on switch?

Since I have to Internet/Mail order, I want to get it right the first time.

I'm finding this thread kind of fascinating actually!  If I could suggest my thoughts, I understood you installed the PL whatever number switch and it doesn't work in the center position. Seems like the issue is, we're not sure whether the switch should be on-on-on or on-off-on.  Can't you disconnect the switch and then measure the continuity in the different switch positions.  Either it is ok, or it is faulty.  Maybe get another from the same store, if it measures different you'd have grounds for returning the faulty one.  Or assuming it's not faulty, then you'd know to get the oppositely configured switch.  Just thinking out loud, since nothing so far has solved this.  Good luck!

It is fascinating!  Agree these are the most valuable threads too. Hope it helps someone especially op.

You can try hooking the wires up without a switch and see what happens. If a wire connected to the center lugs wire stops the sound then you need on off on.  If it doesn’t sound unless connected you need on on on. The only question is what it needs for blend mode in the center.

If on off on as suspected it should act in blend mode with none of the switch wires connected.

You want spdt. Single pole double throw.

Dpdt (double pole double throw)will work too but you only need one column or side.

Post pictures if you’re stuck. I’ll be off grid a few days but will check in after.

I sent a mouse-drawn schematic to StewMac



and they came up with this suggestion:

https://www.stewmac.com/Pickups_and_Electronics/Components_and_Parts/Switches/Switchcraft_Toggle_Switches.html

# 1242

It's silver but that's no big thing for me. I'll put a black tip on it.

Thanks y'all for your help.

 Hi Bob, before you hit the buy button check the overall height especially from the collar to the base of the switch. That looks like it’s designed for a thick body guitar like a Les Paul and I suspect it won’t fit in your DF.

Looking at the design and the description I also suspect it works exactly the same way as the PL and the switches on eBay I sent  through. These ones definitely fit.

Cheers,
Jamie

Thanks.

It says "Short" so I took a chance. If it doesn't work, I'll be out $30. I didn't get your advice until after I pulled the trigger.

I only bought one, and if it works, I'll get another two.

The one I got from my local GC apparently was on/off/on. The clerk didn't know, and being a saxophonist who doubles on guitar, I hadn't learned what I needed yet (and am still learning).

I'm still enjoying the guitar, even though I can't dial in the piezo yet.

Ah yes, the short one might be fine. I’ll be interested to hear your thoughts on build quality compared to the PL once it arrives. if it’s better I might swap to these myself next time mine fail.

Will do.

If my guess is right, it will be better. I've relied on Switchcraft jacks, plugs, and switches in other applications and they have been consistently better than average.

I's supposed to arrive in a couple of days, and then depending on gigs, it might take a day or two to put in.

The switch came in. It clicks nicely and looks well built. I'll try to get to it next week. Weekends are for gigging.

I'll let you know.
