What You Need to Know About Membrane Switch

Membrane switch is an electrical switch basically used for making a circuit on and off along

with delivering superior quality and output. These switches are something different from

the normal switches available in the market. They are called the contact switches and

contain a small amount of PCB space compared to the mechanical one. Controlling heavy

machineries is easier with these switches. Let's have a look at the structure and use of these

switches in detail.

Structure of Membrane-switches:

Generally, these switches are the circuits printed on PET or ITO film using the screen

printing copper, silver and graphite metal filling. These switches deliver user commands to

various electronic devices and contain four or more layers in it. The top layer is the graphical

interface that communicates user and the machine. Rest of the layers support the top

graphic layer according to the quality and the functionality requirement along with the

specifications required by the user. LED and some other technologies are used to deliver

back light as these gadgets have graphics and text on the surface.

Regarding the back lights, there are 3 options. The first option is LED (Light Emitting Diode),

second one is Optical Fibre and the third one is electroluminescent (EL) lamps.

Applications of Membrane Switch:

One can find these switches in most of the electronic appliances like, ovens, coffee makers,

etc. Besides, they are also used in membrane keypads, cars, hospitals and most of the other

sectors. Normally, membrane keypads are dust and liquid resistant, so, the use of this

keypad is common in a number of devices like, calculators, remote controls and more.

Advantages:

Membrane switches are the important part of any related device and if it fails to work

properly, then user may not get anticipated success using that product.

These switches are reliable along with contains better integration and execution

ability.

Helps in running and controlling highly sensitive devices or machines.

Due to the increasing demand, the manufacturers are now providing customized

solutions to match the requirements.

Due to the low production cost, these switches and keypads are cost effective.

Dust and liquid resistant along with zero space within keys.

Hassle free to use in the areas where exposure is higher.

Strong back light to see the switches during operation.

Easy to clean and use.

Own requirements can be designed to make any modification.

Can be used as modern PC keyboards.

However, before purchasing any switch, the buyer must be aware about the reliability of the

Membrane switch manufacturer and follow some critiques. It helps in finding genuine and

affordable products online.
