LuxDrive Dynaohm Variable Resistor + and -

Hello from moldy Seattle!

Another one for the W.O.O.F.'s:

Just noticed the label on the LuxDrive 20 mA Variable Resistors indicate plus / in and minus / out legs. Never looked that closely.
If wired into an AV switch, I would assume the plus / in leg is the upstream side, and the minus / out leg is closest to the AV switch.

Is that correct?

If not installed as described above, would they work as intended?

Thanks, as always, and best regards,

I assume you mean this.. 20mA DynaOhm™ Variable Resistor (thecustomsabershop.com)

It only goes on the positive side and there is a IN and a OUT. So in from battery source and out to the LED.

Thanks, Mr. Strydur -

Yes, the same resistor that you sell.
If the ends are accidentally swapped does the resistor still function as designed? Asking for a friend.

I wouldn't think so..

Generally, no they don’t. With those, the polarity matters.

When you are wiring things that are labeled, you can generally assume + should be connected toward the + of the power source and - to -, that's the purpose of those labels.

This item does not have a - label. It has + in and a out.. suppose it should say + out to be less confusing.

It does have the + on it, I guess the - is implied. I actually never noticed that it says in/out. Maybe with my eyesight I just thought "out" was a -!

Just to be 100% clear.. this does not go to negative.. Positive in and Positive out.

This makes sense as Amperage is measured in-line unlike voltage which is measured using pos and neg.
