We deliver customized membrane switches and keypads to ensure that the final product meets all your specifications and requirements. Every customer receives a personalized experience, and once our experts finish their work, they receive a custom solution that matches their applications perfectly.

The key to creating a high-quality membrane switch starts with a high-quality prototype. At the onset of our collaboration, you will receive a prototype that matches the product specifications. Our engineers follow all the safety and quality standards before presenting the prototype.

About Membrane Switches

A membrane switch is a common component of applications used across many sectors, from consumer electronics and industrial environments to medical and military applications.

Membrane switches are made of flexible graphic and internal layers (also called membranes) on top of a circuit. Thanks to their layered nature, membrane switches offer engineers a lot of freedom in designing and implementing solutions that deliver the desired customer experience.

Membrane switches developed by our engineers come with many features that match any custom requirements:

  • Thin and flexible materials
  • Custom design
  • Improved aesthetics
  • Multi-color integration
  • High durability
  • Vast add-on choices

Key Components Of A Membrane Switch

When designing a membrane switch, our experts consider many different parameters, including the intended use cases, graphic overlays, adhesives, and more. Find out more about the components a membrane switch needs to have.

The mechanical design of a membrane switch defines its value. We can design membrane switches to be tactile and non-tactile. We will help you choose the option that suits your application best and matches the desired product requirements.

To improve vision and deliver a better user experience, add backlighting to your membrane switch. You can choose from the best backlighting product suite: LED, thick light guide film. Our engineers know how to precisely manage the light quality, color, intensity, and coverage to achieve the best effect. 

This is the top layer of a membrane switch that serves as the interface between the user and the machine. Pick a material that ensures durability in the application’s environment. Your membrane switch might need to be protected against scratches, chemical abrasions, or extreme temperatures. 

Display Module

This is another important choice in the design of your membrane switch. We know that the right finish is vital and help our customers choose from multiple display options that match their products’ unique requirements.

These are all the additional elements such as shielding, adhesives, venting, pinouts, connector tail, and dome arrays. We can design membrane switches with almost any Surface Mount Device component embedded in them like resistors or light sensors.

Adding a touch panel alongside the membrane switch brings a new experience for users. Our experts will help you choose from a range of touch panels from our collection, including the high-quality Projected Capacitive touch screens (PCAP).

Membrane Switch Constructions

When it comes to membrane switch constructions, you can choose between ones that are simpler and more advanced. Here’s a short guide to each of these types with examples and key considerations you need to make when designing them.

Simple Membrane Switch Constructions

A simple membrane switch comprises three layers:  a screen-printed circuit, a circuit spacer, and a graphic overlay. This option is usually more cost-effective, so its implementation is often dictated by cost-saving measures in the overall product design. 

Consider these aspects:

Tactile Or Non-Tactile Feedback.

Tactile feedback is the feeling users experience when they push a button. You can choose from different materials and sizes for your buttons, and these choices will require different actuation forces for activating the switch.

Tactile Switches

A tactile switch comes with a metal dome or polydome to result in the desired tactile response (and sometimes audible). These domes can be made of different materials and in different sizes to achieve the desired effect. 

Non-Tactile Switches

When these circuits are actuated, there’s no tactile feel. However, you can add a sound or light component to indicate their activation. Depending on your design, you might need to add an electronic shielding technique.

Advanced Membrane Switch Constructions

More complex user interface designs might require more components and result in more layers. Such multi-layered switches may include a type of ESD, EMI, or RFD shielding, as well as embedded components like LEDs, resistors, or light sensors. To make all of these work together, our experts use copper flex or PCBs to develop the circuit layer. 

Consider these aspects:

Copper Flex Switches

Contrary to screen-printed silver, copper flex circuits are made by laminating copper to an underlying substrate. Then experts etch the substrate to leave specific conductive traces. This delivers a more flexible and precise circuit with extended durability.

Printed Circuit Boards

You might need components of higher-density and smaller size for some user interfaces. This is where printed circuit boards (PCBs) and printed circuit board assemblies (PCBas) come in handy.

Application Environment

A membrane switch needs to serve your users for years. It might be used on a daily or even hourly basis. This requires a purposeful design for lifetime actuation, considering the types of durability, materials, and the need for weather sealing. 

How To Install A Membrane Switch Correctly?

Correct installation is critical to achieving the right effect with the membrane switch and getting the most value from your investment. Here is a brief overview about how to install a membrane switch correctly. You can also download the pdf file for step-to-step installation guidance.


Carefully cut & remove 1/8 of the adhesive layers.


Pass the flex cable through the tail exit slot & adhere the switch to the unit's surface.


Position the membrane switch at 30° & peel the rest of the adhesive liner.


Laminate the switch from the side, where you've removed the adhesive layer.


Start using a soft roller by gradually lowering the angle of the membrane switch.


Lamination is over and time to bend the circuit carefully without damaging the switch.
