TWTADE / 2Pcs 250K Ohm Single Linear Taper Potentiometers with on/Off Switch + 2pcs Black Aluminum Alloy knob

Shipped fast & works good for our application still after many months, so I call it good

These are solid on/off 500k ohm potentiometers. Spec'ed right on the money using my multimeter. They're solid and have that higher quality "beefy" feeling. I needed them to repair a lab hotplate & magnetic stirrer. The original pot plastic disk that holds the knob axle & sweeps the varistor... just mashed & cracked. I have a lot more confidence in this one. The knob stem was standard, and I could use the original knob head to keep the cosmetic appearance the same. There's a nice zinc die-cast face to the potentiometer body that also has a raised standoff and anti-rotation tab if the panel surface or a PCB is slotted for it. Otherwise, you can use the extra nut & washer to space it, or easily file it down. I like having them as a pair, even though I needed only one. As I like having spares of EVERYTHING. Not a criticism, just a warning. The pot body is a bit bigger than other B500k on/off pots. It may not fit in all applications. But it fit fine for me since it's essentially a metal box with lots of free space inside. Some sort of rack audio equipment might not.

Just what I needed to fix my grinder.
