Odd post, if you know why people don't use RS pots, then why do you use it.

They fail within a year in EV use, and it is not the thing you want to fail.

If no one uses them then how do you know they will fail in a year? I think the price is attractive. Has acceptable noise. The longer 300 degree throw means a smoother scale. It's the more complicated throw that seems to be the reason no one uses them. I just figured out a way around that. Lawrence Rhodes.........

My friend used one, he's swapping it for automotive pot now. Plenty of
other converters have made the same mistake before you, it is a
frequent topic on this list. They die from vibration, dust and water
ingress.


By the way, you're the one who said no one is using them.....

I used one for my go-kart, its a 300deg audio 0-5k volume control or
something.
I just fixed a lever on to it worked fine for testing, moving to a plunger
type now, with about 1.5" of travel.

Hi Lawrence,

Please let us know your opinion in a year or so.
Issue tends to be that you drive with the pot
mostly in the same area and every movement of
your foot (or handle) will mean that the wiper
will scrape one more time across the carbon layer.
After so many thousands of movements the carbon
is gone and the pot starts to disconnect (scratch)
instead of giving a smooth acceleration.
Depending on your driving style it may take longer
or shorter, just like some people wear their brakes
down after 20,000 miles and others still have life
left in them after 80,000.
Cheap pots usually also have a marginal carbon layer
so they fail much earlier than special designed
automotive pots, besides the (missing) protection
against dust and moisture.

It will be good to know your experience.
