Hall Effect vs TMR vs standard Joy-Con sticks, which should you fit?
There are three kinds of replacement Joy-Con stick on the market: the same carbon-pad design that came with the controller, Hall Effect modules, and the newer TMR sticks. They cost, feel, and last very differently. Here's how to choose.
The Joy-Con drifts. You've decided to replace the stick. Three options confront you at the parts shop or on eBay: a cheap "original" replacement, a Hall Effect module, or the newer TMR type. They're not equivalent. Here's what each one actually is, what it costs, and which makes sense for your situation.
Standard carbon-pad stick (the original)
What it is: the same stick design that came in the Joy-Con. Two carbon-loaded plastic pads slide across a resistive element as you move the stick, producing an analog voltage that the Switch reads as X/Y position.
Cost: £3-8 for a replacement pair.
Carbon-track wear: retained. A standard replacement uses the same contact-wiper mechanism, so service life varies with the part, fitting, contamination and use.
Feel: identical to stock. No learning curve.
When to use: if you want the cheapest possible fix and you're comfortable doing the job again in a year. Also the only option if you're fixing a controller for resale and need it indistinguishable from stock.
Hall Effect stick
What it is: uses a small magnet fixed inside the stick shaft and magnetic sensor chips under it. As you move the stick, the magnetic field changes in a predictable way and the sensors read it as position. No physical contact between moving parts inside the sensing mechanism.
Cost: £12-18 for a drop-in Joy-Con-compatible pair. GuliKit is the most established brand.
Carbon-track wear: removed. Hall Effect sensing avoids the contact-wiper mechanism, although springs, bearings, contamination and calibration can still affect centring.
Feel: slightly different, usually described as a firmer return-to-centre action and a slightly "tighter" motion through the middle range. Most people stop noticing after a day. Some competitive FPS players say Hall Effect feels less good for tiny precision adjustments; that's real but subtle.
Power draw: marginally higher than standard, about 5% more on Joy-Con battery. You'd need to really count your hours to notice.
When to use: when removing carbon-track wear matters and the chosen module is compatible with the controller and calibration method.
TMR (Tunnel Magnetoresistance) stick
What it is: newer technology that detects magnetic field direction more precisely than Hall Effect sensors. Still uses a magnet in the stick shaft; just a more sensitive read-out underneath.
Cost: £18-28 for Joy-Con-compatible pairs. Still newer, so fewer brands.
Carbon-track wear: removed. TMR still depends on compatible mechanics, fitting and calibration, so it is not a lifetime guarantee.
Feel: closer to stock than Hall Effect. The slightly different return-to-centre and mid-range feel that Hall Effect has is largely absent from TMR, competitive players often prefer this.
Power draw: slightly lower than Hall Effect. Marginally better battery life than standard carbon-pad sticks.
When to use: if you're a precision player (Splatoon competitive, Smash Bros, FPS ports) and you want the drift fix without any feel change. Worth the extra £5-10 over Hall Effect.
Side-by-side summary

What we fit
Hark Tech discusses compatible Hall Effect or TMR options after a free photo check. The applicable part category is confirmed before fitting, and no module is presented as a lifetime guarantee.
Will my warranty be affected?
If your Joy-Con is still under Nintendo's 12-month warranty, don't fit any replacement stick yourself, use Nintendo's free repair service. Once you open the controller, Nintendo's warranty is void. Nintendo may use a standard replacement design, whose service life varies, but while the manufacturer route is available it is sensible to use it.
Out of warranty, consider a compatible Hall Effect or TMR module if removing carbon-track wear matters, while allowing for other mechanical, contamination and calibration faults.
When to send it in
Hark Tech repairs one Joy-Con for £35 or a pair for £55, including tracked UK return and a 12-month warranty. Compatible Hall Effect or TMR modules remove the common carbon-track wear mechanism, but other mechanical, contamination and calibration faults can still occur. Request a free photo check before booking; allow 3–5 working days from arrival.
