If you're looking for a keypad, chances are that you want one that is durable and easy to install. You probably also want it to look nice. Surely, you would like the keys to be of good quality and have a pleasant feel when pressed. What about durability? Is the material going to wear out?
Well, these are a few qualities that you can keep in mind when you use a membrane keypad. There are situations when you wish to know about different parts or components of membrane keypads. Here we are going to discuss some of them below.
Capacitive Switch
The capacitive membrane switch is those where the keys are attached to a thin metal plate. These are usually the most common type of keypads we come across. Most of us use them at work and in school, where any number or letter can be entered into the input box. Capacitive keys are commonly used in touch screen devices, including laptops, desktops, and netbooks.
A typical capacitive switch has a thin plastic membrane that covers the switch and metal plates beneath it. These metal plates act as mini switches on which we press our fingers to enter data into a computer or cell phone.
Waterproof Membrane Switch
The waterproof membrane switch keypad is a more durable and long-lasting one, and it is used in conditions where there is moisture. It's a thin film layer that covers all the switches and makes them waterproof, dustproof, and shockproof. There are also other types of membrane keypads like Die-Cut.
It is basically a thin layer of plastic material with tiny holes in it, which are used to identify the keys and enter data into a particular device like a computer or cell phone. The holes are big enough to allow the identification of the character but too small to allow the dirt or dust inside it.
A dome label is a label that acts as a keypad in a very delicate way. It is used to identify the keys and place data into the computer or cell phone.
On these types of keypads, the letters and numbers are molded in a particular shape on which we press our fingers to enter data into a device. The dome labels can be found on touch screen devices like laptops and notebooks.
Graphic Overlay
A graphic overlay kind of keypad is used in those systems that have a touch screen. In these systems, the images of the keys are printed on a transparent plastic layer to make it look like a normal keypad. Then, we press this to enter data into our machine or cell phone.
Magnetic Membrane Switch
This type of ergonomic membrane keypad is one more feature that makes it efficient and durable. The magnetic membrane switch generates a strong magnetic field that attracts and repels at the same time whenever we press our fingers or even hold them there for some time. A magnetic membrane keypad is used in whiteboards and other electromagnetic devices. They are commonly used in schools and offices where any number can be entered into a computer.
