DPDT on/off switch problem
« on: May 19, 2004, 04:52:12 PM »
there are six holes on my switch

1 0|0 2
3 0|0 4
5 0|0 6   <---the right numbering?

i think the 5&6 is for the jumper wiring? or just called bypass

but i don't know the rest, i've tried some stuff on the sight

what will be happening to my 100kpot if i remove the middle wire from the part of the middle ring, and from the DPDT 4th one, and replacing the DPDT 4th part with (where the 100k wire used to be) wire connection to the output jack...

(there is a pic where you put 47K? on the 100k pot...i don't understand)....
i haven't given up just yet!

Hi 9V,

Please reference this forum for the answer on how a DPDT works:

and

Which circuit are you working on?

thanks

i am going to do that FX's Pics of yours DPDT switch links..

it makes sense, just FX in/out - in/out jack - and jumper...

the problem is..... you know a while ago i've posted this website
http://www.geocities.com/CollegePark/Library/1355/beginners.htm

for electra distortion the schematics and the copper tracing layout of the circuit is available on the bottom of the homepage, if you would please take a look, the wiring is totally off, way off compared to the explaination that you drew,

it makes perfect sense, the first row is FXin-out and second row is in/out jack - and jumper thing is 3rd row,

but the 100K wires pot used for electra distortion, will be missing from the DPDT switch and has to be done something right? and i thought i would take a look at the first link of yours and your NPN boost 5k pot has some 0.47k stuck on it on the middle ring(?) of the pot...

oh and also shield sleeve tip ring? what are those?

(input)            (output)
stero jack       mono
I  I                 I
000                00

^^ from looking at that picture??^^^


and some line stating "the connection can be made through metal chassis"
what does it mean by that?

and looking from the layout picture from the site i posted here
http://www.geocities.com/CollegePark/Library/1355/beginners.htm

the ground connection, is there a good reading about this??...and what does he/she mean when saying Large circles for screw and nut and 2 mall for jacks' ground?



thank you

I can't. Everytime I check geocities tells me the quota is over limit and I can't view anything.

I have no idea. I bet the 100K pot is a volume pot so one outer lug is the output of the effect, the other outer lug is ground and the middle goes to the switch.

>and i thought i would take a look at the first link of yours and your NPN boost 5k pot has some 0.47k stuck on it on the middle ring(?) of the pot...

Yes, that's because this booster circuit has a .47uF (not K) capacitor across the lugs. This is different from your circuit.

>oh and also shield sleeve tip ring? what are those?

This is in the DIY FAQ which I hope you have read:

>and some line stating "the connection can be made through metal chassis"

I don't know. A connection through the metal box used for the pedal?

>the ground connection, is there a good reading about this??...and what does he/she mean when saying Large circles for screw and nut and 2 mall for jacks' ground?

Sounds like there are large circles in the picture for screws and 2 small circuits where the jack's ground connects.
