The WH148 is a reliable, general-purpose 10kΩ (B10K) linear taper rotary potentiometer with a 15mm knurled 6mm shaft and a standard 3-pin layout. It is a drop-in fit for breadboards, panels and PCBs, and a go-to part for volume and tone controls, signal adjustment and Arduino or ESP32 analog input. A panel nut and washer are included for a clean, secure mount.

Wiring & getting started

Connect the outer pins
Wire pin 1 to your supply (VCC, 3.3-5V) and pin 3 to ground (GND). Swap these two if the direction of travel feels reversed.
Take the wiper output
Pin 2, the centre wiper, is your output. Send it to a microcontroller analog input (ADC) or the point you want to control.
Read the value
On Arduino, analogRead() on the wiper pin gives 0 to 1023 across the full sweep. On ESP32 use analogRead() on an ADC pin.
Mount it cleanly
Push the shaft through a panel hole, fit the washer and tighten the nut. The knurled 6mm shaft accepts most push-fit and set-screw knobs.

Good to know: This is a linear (B) taper pot, so resistance changes at a steady rate across the sweep. For audio volume where you want finer control at low levels, an A (log) taper is the better choice. Packed and dispatched from our Te Awamutu stock.

Frequently asked questions

What does B taper (linear) mean?

B taper means the resistance changes at a steady, even rate across the full 300 degree sweep. It is ideal for general-purpose control, signal circuits and Arduino or ESP32 analog input. For audio volume where you want finer control at low levels, an A (log) taper is a better fit.

15mm vs 20mm shaft, which should I choose?

The 15mm shaft suits lower-profile panels where the knob sits closer to the surface. The 20mm shaft gives more clearance for deeper enclosures or taller knobs. Both share the same 6mm knurled diameter and are electrically identical.

How do I wire it to an Arduino?

Connect pin 1 to VCC (3.3-5V) and pin 3 to GND, then take the centre wiper (pin 2) to an analog input. analogRead() returns 0 to 1023 across the sweep. Swap pins 1 and 3 if the direction of travel feels reversed.

What size knob does it need?

The shaft is a standard 6mm knurled (splined) shaft, so it fits most push-fit and set-screw knobs sold for 6mm pots. A knob is not included.

Why buy from NZN

International prices. None of the international wait.

We're a small Kiwi-owned shop, and we stock the same boards and parts you'd usually order from overseas, for about the same price. The only real difference is they ship from Te Awamutu, so you get them in a few days instead of waiting weeks.

Run by Kiwis, here in Te Awamutu

We're NZ owned and operated, and every order is picked, packed and sent from our place in Te Awamutu, Waikato.

Get it in days, not weeks

Order before 8am and it ships the same day, otherwise within 24 hours guaranteed. No waiting three to six weeks for a parcel to crawl over from overseas.

Low prices are the goal

As a maker myself, I want New Zealand to have a genuine low-price local option for electronics, not overpriced shelves or a long wait on an international parcel.
