Removing a metal contact changes one wear mechanism, but a keyboard still has moving stems, springs and electronics. The Hall effect switch lifespan should be judged from the whole design and warranty, not a laboratory keystroke claim alone.
Quick Answer
Hall-effect switches sense a magnet without the metal electrical contacts used to register a conventional mechanical switch press, so the sensing point avoids one common wear mechanism. The keyboard still has moving stems, springs, stabilisers, solder joints, LEDs and electronics that can fail. A quoted 100-million or 150-million press rating is a manufacturer test claim under chosen conditions, not a guarantee of your unit's life. Compare warranty, firmware support and replaceability alongside the switch rating.
Contactless sensing has moving parts
The Hall sensor reads magnetic field strength as the key moves. It does not need two metal contacts to close at the actuation point, which can reduce contact wear and chatter.
The key still travels through a housing. Springs can change, stems can wear, dust can obstruct movement and stabilisers can rattle. The sensor and controller also depend on power and calibration.
Heavy use can expose any weak mechanical or electronic part. It does not turn a rating into a countdown.
Read lifetime claims correctly
Ask who ran the test, what counted as a successful press and whether the figure covers the switch alone or complete keyboard. Laboratory cycling does not reproduce spills, side loads, heat or cable damage.
Different mechanical switches have their own contact design and rating. A lower number can reflect the test method as well as the mechanism.
No press rating proves the board will outlast a PC upgrade cycle. Warranty length and service response give you a clearer ownership promise.
Care still changes the result
Keep drinks away, remove surface dust with the keyboard disconnected and use the maker's calibration process. A contactless sensor cannot protect the PCB from a spill or stop debris obstructing the stem.
Use sensible actuation settings. An extreme shallow trigger can make normal hand movement feel like a failing key even when the sensor is healthy. Return to a default profile before opening a support case.
Record firmware and the affected key. Repeatable drift after calibration deserves warranty attention, while one game binding deserves a software check.
Buy the complete keyboard
Check actuation stability, software, onboard profiles, keycap support and current firmware. A durable sensor has little value when the USB port or configuration app becomes the weak link.
Look for independent long-term use reports, but do not mistake one owner's keyboard for a controlled lifespan test. Failure rates need a large, transparent sample.

FAQ
Why can Hall-effect switches last longer?
Their sensing point has no closing electrical contacts to wear or oxidise. The rest of the key and keyboard still ages.
Is a 150-million rating independently verified?
Do not assume it. Read the exact manufacturer source, test conditions and warranty for the model.
Will the keyboard outlast your PC?
It can, but usage, spills, electronics, firmware and repair support decide the real ownership life.
Treat the switch rating as one lab claim, then choose the Hall-effect board with the warranty, firmware and repair path you can live with.
