Help in understanding of wiring diagram

[piton41]

Hello to all on this forum!

I need some help in understanding of wiring diagram i found on thefret.net.



As you see there are 3 SC and two push/pull pots. What are you think is it possible to do like this.
I would like to change these push/pull pots for two SPDT, there is no use for DPDT here ?
Are these switches ON/ON switches because on pictures there is off and on? Maybe this guy thought just if switch is on or of?
This is possible or I'm wrong ?


I've read about switches but I don't understand how to do grounding on two ground wire from neck and middle pickup. They are going on middle lug of Switch 1 and then (please see arrow)? In position off these two are wired to the ground by lug down on Switch 1,and its natural position on body of some pot. In position on (Switch 1) grounding and bridge lead are together is it wrong (or is it serial)?

I know there are many questions, some maybe very stupid but please help if you can...

Thank you

pitty,

I've never seen a push-pull switch mounted to a potentiometer that wasn't DPDT - they all come that way, so far as I know. But remember, just because you have all those connections doesn't mean you have to use them - you can ignore whatever you don't want or need.

But to answer your question, yes you could easily subsititute an SPDT for S1, and an SPST for S2, providing you wanted to use some other kind of switch, instead of a push-pull.

The answer to your other question is yes, you've guessed correctly - pulling up on S1 will put the Bridge in Series with the other two pickups (whichever is selected by the pickup selector switch).

However, there is a potential problem with this arrangement. Can you tell us what happens when both S1 and S2 are pulled up (turned "on")?

I think if both of swiches are "ON" then bridge is in parallel to middle or neck.
I mean you can choose pickup combination with 5-way switch? I can get bridge/neck combo and all tree pickup, I think ?

Piton-

No, with S1 down and S2 down, the bridge is in parallel with the 5-way selection. Pulling up on S1 puts the bridge in series, as intended.

But if you also pull S2 up, you'll have the bridge pickup alone, as the grounds from both the neck and middle pups will then be connected to the output of the 5-way switch, shorting those pickups out if they are selected at the 5-way switch.

There may well be better ways to do this, depending on which combinations you actually want.

So Newey there is no function of S2 if I only get bridge alone in all 5 position or (when on) How can I get can get bridge/neck (telecaster mode) combo and all tree pickup.

Should I remove S2 and wire bridge "hot" lead directly from S1 to 5-way switch ?

Thank you....

pitty,

The only time you "lose" the Middle and Neck pickups is when you pull up (turn 'on') both switches. If you use one or the the other, then you get the various combos, including B+N (the Tele combo).

This is the same problem faced by rabidgerry several months ago. We solved that with a 3 position switch that disallowed any "accidental" engagement of both switches at the same time. But he was working from scratch - he didn't have any parts yet. If you already have the push-pull pots, and you want to use them, then go ahead and do it, there's no need to spend extra money.
