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. ## Features - Product Name : Switch Carbon Potentiometer;Model : WH138 B50k ohm;Technology : Carbon Composition - Rated Power : 0.2W/0.1W;Resistance Value : 50K ohm;Shaft Diameter : 6mm / 0.24" - Shaft Length : 13.5mm / 0.53";Base Height : 18mm / 0.71" ; Knob Diameter: 21x17mm (D*H) - Base Diameter : 24mm / 0.94";Color : Black , Aerugo - Weight : 32g;Package Content : 2 x Switch Carbon Potentiometer + 2 x black Aluminum alloy knob ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FKH6QJ4 | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #31,568 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #18 in Potentiometers | | Customer Reviews | 4.5 4.5 out of 5 stars (395) | | Date First Available | July 13, 2018 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 2 | | Item Weight | 1.58 ounces | | Item model number | 50K ohm | | Manufacturer | TWTADE | | Material | carbon | | Package Dimensions | 2.6 x 2.1 x 1.3 inches | | Part Number | 50K ohm | | Size | 50k ohm | ## Images ![/ 2Pcs 50K Ohm Single Linear Taper Potentiometers with on/Off Switch + 2pcs Black Aluminum Alloy knob - Image 1](https://m.media-amazon.com/images/I/71EF7dTFusL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ A good purchase at a fair price shipped quickly *by A***R on July 8, 2025* Shipped fast & works good for our application still after many months, so I call it good ### ⭐⭐⭐⭐⭐ Sturdy 500k pot. *by A***K on August 8, 2025* These are solid on/off 500k ohm potentiometers.

Used as a replacement switch for my Zadro Lighted Mirror. Switch is flimsy and the connection inside is loose, causing the light to flicker. Since it comes with two switches, I'll try the other one tomorrow. Hopefully it will be better. Update: Soldered the second switch on, works just fine. must have just gotten a rotten one. With that being said, I think this company sent me an extra order of switches. Received them today. That was nice of them. I don't want to change my review on these switches because it was the truth, but I will update the stars from 2 to 4, losing one star for the inconvenience of having to replace the fist one. ## Frequently Bought Together - TWTADE / 2Pcs 50K Ohm Single Linear Taper Potentiometers with on/Off Switch + 2pcs Black Aluminum Alloy knob - TWTADE / 3pcs wh138 10k ohm Potentiometer Single Turn Rotary Linear Variable Potentiometer +3pcs black Aluminum alloy knob - uxcell DC 12V 60N 10mm Stroke Push Pull Type Open Frame Solenoid Electromagnet XRN-1564T --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/106633116-2pcs-50k-ohm-single-linear-taper-potentiometers-with-on-off](https://www.desertcart.uy/products/106633116-2pcs-50k-ohm-single-linear-taper-potentiometers-with-on-off) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-05-27*
