The Hall-effect Switches

Hall effect switches and hall effect Sensor

Hall Effect Key Switch was a luxurious and high-quality switch that was used in the 1980s mainly. It was commonly used in the lisp machine keyboards. [see Lisp Machine Keyboards]

Hall Effect switches are not mechanical switches. They don't rely on physical contact. This could make them more reliable over time. The Hall effect keyboard is triggered using the magnet at the bottom of the switch, and the Hall sensor on the PCB board senses the triggered keys.

Hall Effect switches can also measure the depth of the keypress precisely, and it allows users to adjust the actuation points of these switches, compared to only one actuation point on mechanical switches.


Analog Input 

The Hall switch can now implement an analog input to measure and control the distance between the magnets and the Hall sensor. Hall switches are no longer dependent on mechanical metal contacts. Instead, they use Hall sensors that measure the magnetic field strength to determine the distance a key is pressed. It allows the keyboard to mimic the fluid motion of joysticks or triggers. This innovation makes the keyboard even more powerful.


Advantages of Hall Effect Switches

Hall-effect keys are used in many industries that require high reliability and consistency, including aerospace, military equipment, and submarines.

These industries depend more on accuracy in quantifying velocity, location, and proximity to ensure they function correctly.

You can also see Hall-effect switches in military equipment. These switches are used to detect the rotational speeds of helicopter blades and the position change of the rotational axis.

Hall-effect switches can be costly to produce, but they are also the most reliable. They are guaranteed to last a lifetime because there is no contact that they can wear. Each switch has a rating of billions of cycles, while Cherry MX switches have a rating of 50 million cycles.

The best linear switch is contactless, like a hall effect switch. It's the smoothest.

Standard MX mechanical switches can be more easily damaged by dirt and dust. Keeping them clean is difficult. On the other hand, Hall-effect switches are waterproof and dustproof and are less susceptible to dirt and dust.


Are Hall effect switches considered mechanical switches?

Technically, Hall-effect switches can be considered mechanical switches. Hall-effect switches include magnets in their construction but still have mechanical parts like springs or Stems.

The theoretical advantages of hall-effect switches over traditional contact-based mechanical switches include superior durability, smoothness, a more stable keypress, and a much higher polling rate. It provides a consistent, long-lasting typing sensation!

Hall-effect switches have a considerable advantage in terms of their durability. They are less susceptible to mechanical failure because they do not rely on physical contact, which wears down keys over time. The Hall-effect switch also has fewer parts, which means fewer chances of failure.

Hall-effect keyboards have a second significant benefit: they offer more excellent switch stability. They reduce bounce and chatter by eliminating most of the wobble with very tight tolerances.

Another significant benefit is that it also allows for actuation point customization.

It allows users to mimic the effects of multiple key switches in their hands. You can make some keys lighter (such as the AWSD keys), which aids in fluent movement in FPS games. Gamers and typists who press their keys harder can make their switches heavier.

There are many more possibilities for the Hall-effect switches that are waiting to be discovered.


Disadvantages of Hall-effect switches and solutions


Many have mentioned two disadvantages of Hall-effect switches: their vulnerability to magnetic fields from outside. The second is their susceptibility to thermal drift caused by changes in environmental conditions.

These were the primary considerations when designing the Hall Effect Switch keyboard.

We have taken most of the magnetic field effects out of our keyboard using the unique protection design of the aluminum shell and a Hall induction element. The keyboard can hold a giant magnet, but the hall-effect switches will not be adequately functioning long-term in a solid Magnetic field. Headphones and speakers will not interfere with regular keyboard use according to a laboratory test.

We knew that thermal drift would occur, so it has also been a concern. To ensure that thermal drift doesn't significantly impact product life cycles, we use unique magnets and hall sensors. We also have a Hall sensor calibration function to address this problem further.

We will make more types of Hall effect switches for customers to choose from.

The selection of Hall-effect switches currently available is limited. There are very few brands that are manufacturing them.

Hephboard will be working on different Hall-effect switches and will strive to offer more options on the functionality to support various users.


Are Hall Effect Keyboards Good For Gaming and Typing?

Hall Effect keyboards are very like mechanical keyboards in appearance and feel. They can be just as effective as mechanical keyboards for typing-related tasks, as well as gaming.

Additionally, because Hall Effect Keyboards allow the user to control the force of actuation for the switches, they can mimic the majority of most popular mechanical switches on the market. No matter if you like the feeling of bottoming out on the keys or gently tapping them, these keyboards will accommodate all styles of typing.

The Hall-effect switches could perform with more superiority in certain aspects when gaming. For example, Hall-effect keyboards inherently eliminate chatter on keys due to switching design. They're also durable so the repeated presses will not wear them down.

Also, Hall-effect switches feature less delay in the keypress, when compared to conventional mechanical switches, which have a "debounce delay" (the keyboard must wait a bit to determine whether the key is being pressed.)

Our Hall-effect switches also have a lower trigger latency than standard mechanical switches with a “debounce delay”.

And Hall-effect switches are an order of magnitude faster than MX switches, providing a lag-free input experience for Hall-effect switches keyboards.


Efficient office capabilities and system compatibility

We added H1 to provide a better gaming and typing experience. The metal knobs in F1-F12 can be used to freely define the most efficient shortcut key functions for Windows and Mac systems. It will keep you on the right path with your creativity flow. Keep watching our video guides to software for more information!
This Hall-effect switch has analog input as one of its most remarkable features. We want to make it easier for users to use the Hall switch function. Users can drag and drop modules to perform their functions in different environments and applications without writing codes. It is our most exciting feature and is one of the leading software projects we are currently working on. Please get in touch with us at if you have additional features that you'd like to see on the Hall-effect keyboard.
