I'm about to solder all the pots to the sagan delay vero board  https://tagboardeffects.blogspot.com/search?q=sagan+delay

before I do that I have noob question regarding the rotary switch numbering.

How can I know I do it the right direction and not up side down ?
this is how I number it: https://imgur.com/a/fWCpR7t

is it correct ?

also regarding pot numbering is it right the when you look at the back of the pot the numbering is 3 on the left, 2 in the middle and 1 on the right?

Thanks!

as for the switches - we can't tell you. use your meter so you won't make ANY mistakes.

as for the pots - they don't have numbers. learn counterclockwise, wiper and clockwise, and never be pot confounded again. head to geofex for the secret life of pots, and learn more!

Look in the side of that type switch while you turn the knob; you can see what connects to what.

How that translates to some random "layout" from the web is often a deeper mystery.

Thanks! I check it with multimeter and it seems I connect it all right! I've got another question regarding the dpdt momentary footswitch. if the numbering goes as follow: https://imgur.com/a/UnIOArD

which leg of the dpdt fottswitch I should connect the "Tails SW LED +" ? is it to lug number 5 ?  see picture: https://imgur.com/a/UUgKrEj

So if I number the dpdt correct, the Tails SW 1 goes to lug 1, Tails SW 2 goes to lug 2, Tails Sw 3 goes to lug 3. but what about lug 4, 5 and 6 of the dpdt? is not so clear from the veroboard layout.


and the LED + should connect where ?

Thanks for help!

Edit: Another question regarding grounding: In the vero layout is written that Level3-1, Level 2-1, Level 1-1, Fdbk1, Mix-1, all need to be grounded. Can I just connect them one to each other and the last one to a ground point in the veroboard with a jumper? Should I also ground the entire enclosure?

keep checking with the meter, we can't tell you. see here:



C&K make switches properly - this is not one of theirs, but heyho. on a decent quality toggle switch, how it works will be indicated on the side. see it has (on) off (on)? the brackets mean momentary/spring return. for latching one way, centre off and mom the other, it would read on off (on).

however. you ask about push types. decent quality momentary switches will have it marked on the side, but in different language. this time it will read C NC NO, for Common, Normally Closed, Normally Open. this means when you pick up the switch it is in its normal, resting state and the common terminal will be shorting to the normally closed terminal. when you push it, it changes over the contacts, which is why you might see "double pole change over".

really, switches are the most simple of all circuit elements, and once you learn how to draw them electrically, in a circuit diagram, the mystery falls away and you can see for miles and miles and miles and ....... [he fades out slowly].

as with pots, the numbers mean nothing. they tell us nothing of the function of the switch. however, you can usually assume with these dias that 1, 2, 3 will be one pole and 4, 5, 6 will be a second pole, and 7, ate, 9 will be a third pole ( and that 1, 4 and 7 will all be at the same end/in operation at the same time ). assume, please note. IN EVERY CASE, your meter provides the definative answer.

and as for ground - is ground is ground is ground is nought volts is earth is common [!! NOT switch common !!] is chassis even. all points named ground connect together, in some low resistance form or method.
