Tactile Membrane Keypad: Pros and Cons of Tactical Keyboards
Tactile Membrane Keypad depending on the position and arrangement of these internal components, different switches will give different typing feelings. But in principle there are three basic types of mechanical switches: clicky, tactile and linear. In which Clicky gives a strong, sharp touch, in the middle of the key stroke there is a clear notch accompanied by a loud sound.
Tactile gives good touch still has a notch but the sound is much smaller. The Linear switch is completely smooth, tactile, has no rattle, and is completely quiet. Depending on the resistance of the spring on each type of switch, the force required to receive the key will be different on Tactile Membrane Keypad. The shape of the stem and the design of the housing will determine the actuation distance and travel distance of the keys.
Comparison between mechanical and membrane keyboards
Mechanical keyboards compared to membrane keyboards and dome-switch keyboards are superior in every way. They provide longer life, accuracy, faster typing speed, and a much better click feel.
Since its inception, the mechanical keyboard has gone through a long history and created a world. The have created an ecosystem of its own with diverse switch brands and a variety of mechanical keyboard brands from famous to famous.
What is buckling spring keyboard?
Buckling spring technology was patented in the US for the first time in 1978. To this day, there are still many typing and coding professionals. They love this buckling spring keyboard other than Tactile Membrane Keypad technology. The mechanism of the buckling spring is based on driving a small hammer. It is to strike a capacitive or membrane switch to create a contact where the key is pressed.
How to make a silent Unicom Buckling Spring Keyboard?
The first keyboard to use a buckling spring switch was the IBM Model M. After many production model conversions, the original design and some trendy modifications are still available on Unicomp keyboards.
Hall effects keyboard
Hall effects keyboards use Hall effects sensing magnets instead of switches with normal mechanical contact. When the key is pressed, a magnet moves inside and that movement is detected by a solid sensor. In principle, this is also a type of Tactile Membrane Keypad in which there is no physical contact in the operating mechanism, so the accuracy and durability are very high.
What Are Hall Effect Keyboard Switches, And How Do They Work?
Hall effects switches are common in high-end keyboards and in high-reliability equipment such as nuclear plants, aircraft cockpits, rockets, etc. They are completely impermeable water, dust-free and unaffected by outside temperature and humidity. And of course the price to make these keyboards is extremely expensive.
Laser projection keyboard
Laser keyboards work on this principle: a device the size of a microscopic computer mouse projects a laser beam that projects the shape of the keys onto a Tactile Membrane Keypad. And users type on it like a real key simulation. When typing anywhere, the laser is covered there to help the machine recognize the signal being pressed.
Virtual Laser Keyboard
Although modern, the operation mechanism is simple and extremely convenient, suitable for all terrains. But the laser keyboard also has many major shortcomings that need adjustment in the future if it wants to be more popular: the stability of the keyboard. Laser, keystrokes are prone to errors and wrong keys, if the laser transmitter is malfunctioning.
Optical keyboard technology was first introduced by engineer Harley E. Kelchner in 1962. This optical technology uses a light emitting device and an image sensor to detect optically activated keys on Tactile Membrane Keypad. Usually the emitter and sensor are placed opposite each other, on a small PCB perimeter.
The light comes from side to side under the key in normal mode. And when pressing the key, the down key will push a horizontal lever to obscure the light’s flow. Moreover, it helps the sensor to recognize the change of light illuminates and recognizes a correspondingly pressed character.
What do you know about optical switches on keyboards?
The original optical keyboard designs were very thick, and the keys were extremely high to accommodate the internal light flow under the keys. But now the design of the optical switch and the keycap structure has been greatly refined and become more modern.
If you put a mechanical keyboard and an optical keyboard on the table, you won’t be able to tell the difference if you don’t say it.
Advantages of the optical keyboard: similar to the capacitive, Tactile Membrane Keypad, Hall effects models above, the optical switch does not have direct metal contact. So there is no friction, the key press is light; the key is soft and light. Light, removing iron ghost. So it is extremely durable, has good water resistance, dust resistance and is not affected by outside temperature and humidity.
Which keyboard is the better option?
Above are the switch technologies common for classic and modern computer keyboards. A short sentence is that if the small budget does not require long-term durability, then buying a membrane keyboard is fine. But if you want to save long, wear durable clothes and need a good typing feeling, high accuracy; it must be a mechanical keyboard.
The capacitive and tactile membrane keypad is also well worth the experience because they feel very different, but cost a bit more. Because of the constant development in this day and age, choosing a mechanical keyboard or a rubber membrane keyboard is really a question worth debating.
Comparison of rubber membrane keyboards and Tactile Membrane Keypad
Benefits of rubber membrane keyboard: Because it is a rubber membrane, the typing sound is very small. In general, there are many types of membrane keyboards on the market, so they are easy to find with models to suit your needs. Rubber membrane keyboards are usually very cheap because the materials they are made from are very common but less durable.
Benefits of Tactile Membrane Keypad: Faster typing speed and much longer lifespan. The average lifespan for each mechanical switch is about 50 million keystrokes. And a rubber membrane keyboard will never have that kind of life. The feeling of typing is better, happier and more specific on mechanical keyboards. Something that rubber membrane keyboards can’t have.
What switch to choose for office mechanical keyboard?
Group 1: the switch has a clicking sound
This type of typing is very good, very pleasant to the hand, but the bad point is the loud noise because this type simulates the feeling of a classic typewriter. This group of switches is for those of you who love the typing feel of a mechanical keyboard. They partially simulate the feeling that typewriters bring. Some types of switches we mention: Cherry MX Blue, Gateron Blue.
Group 2: switches without clicks but with tactile
In tactile membrane keypad, tactile here is a small feeling like a notch on the tip of the finger when typing. This feeling is quite similar to the switch with group 1 click but not as clear. In return there is no click sound that makes colleagues angry because of the noise as the switch has a click. This group I strongly recommend for those of you who like the feeling of muscles but don’t like the noise.
Group 3: quiet switch
This group of switches has many different levels from Red being the least Silent to Topre being extremely quiet. This group is extremely quiet and versatile as you can use it from the quiet office to at home without fear of disturbing anyone.
Why tactile membrane keypads are popular?
Have you ever heard of a tactile membrane keypad? Well, they are in great demand by the gamer community for their various advantages and, mainly, their design.
As they have lighting, it ends up being easily accessible, as it is easily visible, convenient to find, whether during the day, afternoon, night or even at dawn. Among them, there are backlit and backlit keyboards.
How does tactile membrane keypad work?
On tactile membrane keypad, light passes through the letters, causing the keys to light up. On the backlit keyboards, the light is between the letters, so they don’t pass through them. This type of keyboard is extremely common in notebooks and gaming computers.
Also, in tactile membrane keypad, they come with a red light that helps players a lot when it comes to gaming.
Some models even have a command that turns off the light, so the lighting does not stay on during the day or during the game, which can sometimes be annoying, depending on the player.
Let’s see some ways to be careful with tactile membrane keypad?
Illuminated keyboards use more battery due to illumination, did you know?
Some keyboard models have cables. They plug directly into the USB on the PC or notebook, while others are wireless, requiring batteries or batteries.
In order not to experience inconveniences during the game and not to be on hand, it is important to always keep the charger close by so that it does not turn off due to lack of battery.
