5 Steps to Fix Tactical Membrane Switch: Types of membrane Keyboards
As a tactile membrane switch mechanical switch, changing the switch is easy and here are all the steps you need to know:
Step 1: Remove the keycap
Use the key puller to remove the keycap from the switch. Sometimes the switch will follow your keycap if the keycap is too close to the switch and this is completely normal. With long keys like the space bar, you remove the keycaps around first and gently remove the keycap from the switch.
Step 2: Remove the switch
Use the switch puller to press the 2 levers on the top and bottom of the switch as shown. When they are pressed in, pull up to remove the switch from the switch. The switch remover can scratch your plate, so handle it carefully when removing the switch.
Step 3: Adjust the 2 pins on the switch
Before attaching new tactile membrane switch, you must make sure they are compatible. Look closely at the copper pins underneath the switch and they should be perfectly straight. Sometimes during transportation or improperly attaching the switch, the switch pins may be bent. The switch pins can be repositioned easily by using tweezers.
Step 4: install the switch
Align the switch on the switch mounting hole and mount it straight down. When pressed down, there will be a little resistance, press down a little more and the switch will lie neatly on the switch. You should open typing software on your computer to make sure the switch works when you press down.
Step 5: Install keycap
Once you’re sure the tactile membrane switch is properly attached, snap the keycap back into place. Changing the switch on the mechanical switch is not difficult, just pay attention to some important points such as the switch leg must be straight and there is no foreign object inside the socket before attaching the switch. And don’t forget to carefully read the user manual that Glorious gives you in the box.
The keyboard is the most popular and effective method of communication between humans and computers today. As fast as computer technology changes, so does keyboard technology. There are many ways to classify computer keyboards, but the most basic and obvious is still to classify according to the switch technology common under each keyboard.
Types of key board
- Normal keyboard
- Membrane keyboard or tactile membrane switch
There are two sub-branches in membrane keyboards:
- Flat-panel membrane keyboards
- Full-travel membrane keyboards
Flat panel membrane keyboard
Flat membrane keyboard is often common as a control panel on microwave devices, copiers. The design of this type of flat membrane keyboard usually consists of 3 layers. The top layer is the button function name character labels printed on the front, and the back is metallic conductive stripes.
The bottom layer has printed metallic conductive stripes perpendicular to the stripes of the previous layer. When given the opportunity to make contact, these stripes coalesce into a net. When the user presses a key, the contacts of the front and back layers form a closed circuit, signaling to the computer or processor that a character has been pressed.
Structure of flat membrane keyboard
The flat membrane keyboard has no specific haptic feedback, the buttons are sometimes raised slightly above the ground, or even flat that can only be known through the characters printed on the top. So control panels that use a flat membrane switch or tactile membrane switch will often need to come with a button that lights up and/and beeps when the key is pressed.
Full-travel membrane keyboards
It is the most popular type of computer keyboard today. The structure of this keyboard includes character keys as we often see today; below the keys is a piece of contiguous plastic switch. And the same principle of operation as above, that is, when the key is pressed, the contact is closed to help the computer recognize the character being pressed.
How long does it take for water spill to permanently damage keyboard?
Membrane keyboards are popular because they are easy to manufacture, low-cost, and can be combined with many different designs. The downside is that the quality, durability, longevity and accuracy are not high.
What is Dome-switch keyboard?
The dome-switch keyboard is somewhere in between flat-panel membrane keyboards and standard mechanical tactile membrane switch keyboards. Its working mechanism is based on bringing two circuit board marks into contact under a rubber or silicone keypad using metal or polyurethane dome-shaped switches.
The metal dome switches are made up of a piece of stainless steel. On pressing the key will give the user a very positive and sharp feeling. Keyboards using metal dome switches are also quite common. The polyurethane rubber dome switches are bubble shaped inside and coated with graphite. Of course, this type of keyboard is a lot cheaper than metal dome switches.
What is Scissor-switch keyboard?
This can be seen as a small classification of the dome tactile membrane switch keyboard above. The keys are mounted on the keyboard via two “scissor” interlocking plastic pieces, and then fastened and the key and keyboard. This type of keyboard still uses a rubber membrane switch but combines with a special “pull” mechanism that links the keycap to a plunger.
Scissor keyboards are often more expensive than dome switch keyboards because they are more difficult to manufacture and go through more stages. Cleaning these keyboards is also a bit more complicated because of the low height of the keys and a lot of contact points.
What is capacitive keyboard?
The operation mechanism of the capacitive keyboard is quite special compared to the above types. Pressing the key changes the capacitance of a sample of capacitor plates. The design of the capacitive tactile membrane switch consists of two pieces of D-shaped capacitors, printed on a PCB and covered by a thin film. The insulating part of the solder acts as a dielectric.
In general, the design and structure of the capacitive switch is quite complicated and difficult to explain in words. The result of this sophisticated operating mechanism has created switches that do not really have contact points and can completely interfere with the key receiving point via the included control software. When typing on this keyboard, it feels soft, light, very fast and very accurate.
What is Topre Switch?
The first keyboard made in this capacitive style was the IBM Model. But it was the Topre tactile membrane switch company who really brought this line of strange, mechanical, non-membrane switches to the world to help people. Know and love more.
Switch Topre has had a few modifications compared to the original capacitive switch: using a spring connection. Under the rubber dome, the dome provides most of the force to keep the key from being pressed, and the spring is common to perform capacitive actions to identify the key press.
Focus on tactile membrane switch responsiveness
To choose your mechanical keyboard well , focus on its type of switch, which will determine the responsiveness of the key and the feeling when typing. Here is an overview of the available options:
Mechanical keyboards with tactile switches. When typing, the stroke (distance of pressing the button) is done in two stages, flexible first, then harder when the command is activated. This feeling remains the key asset of this type of model.
Mechanical keyboards with linear switches. Typing requires the same pressure from start to finish, so there is no announcement of activation.
Mechanical keyboards with click switches. When the command is activated, the button clicks.
The general quality of the tactile membrane switch
Before purchasing your mechanical keyboard, check the general condition of the tactile membrane switch. Mechanical keyboards are known to be robust compared to their standard counterparts. Their quality is mainly based on the materials common.
The strongest have a brushed anodized aluminum or hard plastic frame. Also choose models that are splash resistant. Be aware that the durability of the material depends greatly on your care during maintenance.
Avoid using spray cans as much as possible, so as not to damage the springs of the switches. However, do not hesitate to regularly clean the interstices of the keys with a cloth.
Comfort of use and practicality in tactile membrane switch
A good mechanical keyboard should be comfortable. Who says comfort says good responsiveness. Make sure that the keys respond correctly to the keystroke. You don’t have to press a key to complete a command.
The comfort of the model is also reflected in the presence of a wrist rest, especially if you are considering marathon use of the equipment. On the practical side, pay attention to the length of the wire or opt for a wireless mechanical keyboard. But be careful; make sure that this characteristic does not affect the tactile membrane switch. Finally, the best devices of this type allow you to program macro commands via certain keys.
Design, another criterion of tactile membrane switch
Last but not least: design. You will find futuristic mechanical keyboards as well as minimalist models on the market. These simply take the design of classic keyboards. If you like customizable models, some brands offer backlit keys.
This endlessly multiplies the possibilities with more than 16 million colors. Whatever the aesthetic bias, a good mechanical keyboard should be ergonomic to make it as easy as possible for you to use. The most popular have, for example, a tactile shortcut unit in addition to the usual keys.
