Membrane switches are devices for actuating
a circuit and is finding a wide application these days due to
their aesthetics, ease in operation, better functioning and
durability. The membrane switches are Dust tight, Water
resistant, Chemical resistant, Long-lasting, stable operation in
wide range of temperatures, aesthetically pleasing, economic and
slim-line. It can be customized according to the need with a
wide range of features. These days it is in fashion and
replacing the old switches. to provide ease, aesthetic look and
accuracy in their operation. These membrane switches are made
from high quality material and most suitable for use in hi-tech
equipments and weapons. These can withstand rough environmental
conditions, vibration, and rough use and can be trusted in time
of war. Our experts help our customers in choosing the right
feature with these membrane switches according to conditions of
use and application.
Defination
Membrane switch is a device used for turning on and off any electrical device and in this a circuit is printed on a PET or polyester and the ink used for printing is filled with graphite, silver or copper to make it conductive. Top layer of the membrane is used as interface between machine and user.
Shakti Keypads manufacture and supply a wide range of membrane switches which are of superior design and material. It is manufactured by best technology machinery. These membrane switches are very attractive, sleek, convenient and high performance and durable. It makes your machines and gadget look modern. It is available in customized designs and features according to the need of customers.
A membrane switch has generally 5-6 layers. A typical membrane switch has following layers:
- Graphic layer
- Graphic adhesive layer
- Circuit or PCB layer
- Adhesive separator layer
- Optional second circuit or PCB layer

Construction of Membrane
Features
Membrane switches are available with wide range of features. Different applications need different types of features i.e. in some application we need feedback and in some we don’t , some products are for rough use and some for light use, some need more light and some less etc. The switches are added to the product according to the need of product as well as customer.
Tactile Membrane Switches
These are switches which provides a feedback i.e. positive snap or pop action when actuated. This can be achieved by embedding stainless steel domes in the membrane switch or polyester domes formed in either the circuit layer or the graphic overlay.
We offer a wide variety of tactile switches of different size, shape, actuation forces, dome etc. Our experts suggest the clients about the suitability of tactile membrane switches according to their need. Our design is excellent and very good in performance, use and very attractive in aesthetics.
Non- Tactile Membrane Switches
These switches do not provide direct feed back when actuated. So, these non tactile membrane switches are used along with LED indicator or any audio stimuli for feedback.
We offer a wide range of non-tactile switches according to your need. These switches are economical, durable and suitable for places of harsh environmental conditions and errant electrical charges. Our experts suggest the suitability of these switches according to the application. We provide best design to our customers, which is very simple and attractive.
Membrane Switch with EL Backlighting
Lighting of the switches is very necessary in low light environment as well as it gives a very good visual effect. In this backlighting we use electroluminescent technology in which the special material used, emits light when electric current is passed through it.
We use printable ink deposit to illuminate the membrane switch. These membrane switches are useful for mobiles, pagers, laboratory equipments etc. Our experts suggest the suitability of this membrane switch according to application. We provide best El backlighting as we have expertise in this technology.
Membrane Switch with LED Backlighting
I.In this membrane switch we use light emitting diodes for backlighting purpose. This switch has brighter light, longer life, lower energy consumption, grater durability and faster switching. These has application in telephones, calculators etc. We advice the customer on the basis of their requirement and provide them with customized product. Our technology is very advanced the product we manufacture is very long lasting and high performance.
Embossed and Debossed Key
The keys of the membrane switches are raised above the surface then it is embossed and when it is depressed below the surface then it is debossed. This increases tactile recognition as well as increases aesthetic look of the product. We offer a wide range of emboss and deboss design membrane switches which enhances the look and is convenient in use. These switches are designed according to the application and choice of customer. Our experts offer advice and help the customer in choosing the right design.
Types of Membrane Switches
Membrane switches are of two types depending upon the nature of their construction. They are constructed according to the requirement or application.
Flexible Membrane Switches
Our flexible membrane switches find application in a number of control panels like that of micro wave,air conditioner,TV remote etc. It has features like easy to install,clean,sealing ability,shock resistant,low abrasion,lightweight,small in size,longer life,low profile etc. The scope of application of our switches is wide and are used in ultrasound probe,industrial equipment,aerospace industry,manufacturing industry etc. These are highly flexible and can be bent and twisted without damaging the conductor. Designed and manufactured using latest technology and best quality raw materials.
Rigid Membrane Switches
Our Rigid membrane switches use rigid copper leads on PCB instead of the usual silver ink printed circuit boards. These switches are highly suitable for applications involving complex circuit layout or wherein many components like LED,resistors,chips etc have to be connected together. Highly durable,longer life,shock resistant,small size etc are the features. Designed by expert engineers and manufactured using state of the art facilities. The manufacturing process is carried out under stringent quality checks from the first stage to the last stage.
