Innovative Switches in a Stunning Acrylic Body

The Hall sensor, for which this innovative keyboard is named, was popular in keyboards of the 1970s and ‘80s thanks to its reliability. Frequently used in nuclear reactors, missile silos, and aircraft cockpits, the sensor steadily became less popular due to high cost of production. Lucky for you, we’re bringing it back with this keyboard from APT, available in five layouts with your choice of linear of clicky switches. This version has some key improvements, including an EVA foam piece at the bottom of the magnets to reduce noise when pressing down, another piece of foam between the housing and the slider to reduce noise when the switch comes back up, yet another piece of foam added to the end of the wire to reduce noise from pressing down on the plate, plus a longer slot for the spacebar to improve smoothness.

Note: The base price is for the acrylic or teak one-piece 61-key keyboard. At checkout, you can choose a one-piece acrylic keyboard with 87 keys (+ $15), 98 keys (+ $15), or 108 keys (+ $20). You will also have your choice of linear or clicky switches. 

The Hall Effect: A Bounce-Free Magnetic Switch

Most keyboards on the market use a rubber dome and membranes, a physical switch, or a capacitance sensor to detect key position. The APT Hall Effect uses magnets. Compared to a mechanical switch, the Hall sensor is inherently bounce free and water resistant, and it offers short response time. Key action is super smooth because there are no contacts being brought together. Plus, since there are no contacts to wear out, the keys will last a lifetime (or as long as the magnet stays strong and the plastics don’t wear out).

Additional Details

The APT Hall Effect keyboard is fitted with brilliant RGB backlighting, which, when paired with the acrylic case, will really pop off your desktop. The oven-soldered circuit board also offers a host of colorful modes to set the tone in your setup. Plus, each key is LED customizable to your exacting standards. PBT/POM doubleshot shine-through keycaps help further illuminate the keyboard.

Okay, I'm back after a few days with a comment - AND a request. My 108-key round-2 keyboard was delivered October 24, 2018. Today's the 29th. It's every bit as awesome as I mentioned earlier. However I am noticing one little issue, one that only promises to worsen with time. The bottom of the keyboard has three supports in front (closest to the spacebar) but only two (closest to the function keys). It's heavy - which is great - but unfortunately the keyboard's already begun to sag. The keyboard is rests on my thick, glass desktop - flat as it can get - so it's easy to notice. Looking at the keyboard in its as-used position, the line from the top right key (Cal) to the bottom left key (Ctrl) becomes the fulcrum of the sag, lifting the bottom-right support ever so slightly above the desktop. It'll only worsen over time. (Would the sag strain the circuit board, long-term? Can't say.) The solution, of course, is the addition of third support where there are only two today. So, here's my request. Can I obtain an additional plastic support and matching rubber foot? To be clear, I'm talking about the taller plastic support found beneath the function keys. I seem to recall pictures of the round-1 keyboards having a rear support that was basically a stack of acrylic running the length of the keyboard. While the round-2 support system is far superior in appearance it's lacking in... support. If an additional support's not available I'll have no choice but to fabricate one. My gut says I'd probably measure an existing support and turn some brass or aluminum stock on my lathe to duplicate the appearance. Even with this flaw, this is still the best keyboard I've used in decades!
