Inductive Key Switches (Aesco a83)

[tp4tissue]

There was an obscure post 6 years ago on Reddit.

But now it's an actual product.

The switch center has a metal rod, the rod goes through a printed coil on the PCB, the AC current in the coil actively monitors the change in the field.

Pretty cool, it says the main benefit is standardizing switches so anyone can make a hotswap version, as opposed to hall effect which is extremely difficult to standardize.


It also mentions greater stability, Tp4 is not sure why this is inherently more stable, perhaps they mean they can achieve a tighter tolerances making the metal rods vs magnet slugs.

Anyway,  Pretty cool. Pretttty expensive, Direct from Aliexpress for $160ish.

I mean, all things considered, Fully suspended gasket mount, supports 8k polling wired, 4k polling wireless, 300h, 10000mah. You can give your money to razer and buy their old jank for a whole lot more.  And holy crap does this keyboard use an insane number of chips. You can see the back of the board pcb in the teardown video below, 1min 52 sec.
