Taiss 2pcs RV24YN20S 20K Potentiometer Single Turn Carbon Film Rotary Taper Potentiometer Used for Inverter speed regulation. Motor speed control + 2pcs A03 knob + 2pcs dials (B203 20K ohm)

I am impressed with the feel and quality of these potentiometers. When you turn the shaft, it is very smooth and has just the right amount of resistance. It also appears to be sealed. It is not rated for moisture, but it looks like it may be good if you apply some sealant on the back metal. All in all, I do like these. Having the knobs included is a big plus for me.

OK

It works. I had to replace the potentiometer on my variable speed bench grinder. The issue with this unit is the 3 terminal contacts. They are very thin gauge and so I couldn't find female connectors that fit snug onto those contacts. They would barely make contact and slip right off. I had to get out the soldering gun and solder the wires directly on the contacts. (Loop the twisted bare end through the little hole on the contact, double it back and twist the bare wire together. Then solder it to the contact). If the 3 contacts were a little thicker, then a standard female connector would work, so that's the reason for 4 stars instead of 5.

I needed replacement input controls for a power amp and these are better than the original parts. They are high precision, well built controls, basically sealed, with no openings for dust to get in. They have a nice, solid feel to them when you turn them, the resistance varies smoothly with no jumps or gaps, and they are quiet! I haven't seen controls of this high quality available as a new part for many years, they look like the ones found in old test equipment. I am very pleased!

Worked perfectly for fixing a broken wattage variable on a linear amplifier, great price & good quality product.

Wrong size for what I needed but that was my fault. They are very well made and do not feel cheap.

The shaft shown is not the one I received.

Using on my Hobart Handler 210 mig welder and so far it's been working good.
