General wiring diagrams

Yes, led and led resistor can be left iff the board with #3. There are some boards that don't have either and LED or the accompanying resistor in the board, use #3 if this I the case and you want an LED indicator.

Just to confirm, is the stereo jack the input?

Also, if I were to leave out the 9v battery harness, how would I go about doing that?

Thanks!

If you don't plan on using a battery, than you can use a mono jack at the input. If you already have the stereo jack, just leave the ring disconnected and wire it up like normal.

What is the purpose of grounding the input when bypassed?  I've noticed other 3PDT wiring diagrams that don't do this so I was wondering the difference?

Thanks,

Hate to be dense, but what is done with the sleeve connection on J1 which is output, correct?

Is it left open?

Missed this one, sorry. Here's the late info.

Grounding the PCB's input while in bypass is helpful for draining current from some of the electrolytic capacitors which store electricity. This leads to two things (as far as I know) - prolonged life for the caps, and less or no popping when turning the circuit back on.

You're not dense, you just haven't learned yet! No worries!

Often we all use the open switchcraft jacks. Many jacks actually connect to ground through the enclosure because it's metal. That means that technically you only have to connect one of the jack's ground lugs (sleeve) to the PCB ground. I do this all the time. However, remember that if you remove the circuit from the enclosure, you now need to find a way to ground that jack.

I try hard to connect all ground to the PCB. For example, if there are extra 'holes' for the ground, I will use one for the switch, one for the power jack, and then one for either jack. That way, I only need to run one wire to each lug. Many problems while wiring occur because you're trying to fit too many wires onto a single lug which isn't meant to handle more than one wire, like Power jacks. That's also why i like having the CLR and a hole for the LED on my board, that way I don't have to solder two wires to the power jack.

That makes a lot of sense. Thanks for the knowledge.

Hey there, I'm working on my first project and got to the 3pdt switch. I think I understand the wiring alright but I'm just not sure which way is up on this switch according to the way the diagram. Is it basically reversable?

sorry for the noom question.

[jkokura]

Switches can be reversable, but only up and down. You can turn a switch 180 degrees, but not 90 degrees.

The holes in the lugs need to be seen through top to bottom. That means that all the holes go up and down. Does that help?

I "think" I get what you mean but not sure. I understand the "You can turn a switch 180 degrees, but not 90 degrees."

But the holes need to be seen through top to bottom? Are you saying that the holes in the switch need to face the top/bottom of box? Thus the holes do NOT face towards the input/output jacks?

[jkokura]

Yes.

Thanks.

Is there a smiley with a light bulb going off over a head?

Here is a new wiring diagram I put together. I will be referring to this one in future documentation in the hopes of eliminating the redundant diagrams in each project.

looks awesome!

[petesz]

That looks fantastic, will make it heaps easier for anyone starting out for sure (and ofcourse ill be printing it and sticking it on my bench ).
