What is a Membrane Switch?

A membrane switch is a user interface that utilizes circuitry printed on layers of flexible polymer film.  When actuated, the membrane switch circuitry is momentarily closed and provides an electrical signal to the main circuit board.  Membrane switches typically have several layers that incorporate a graphical interface with an electrical circuit.

What are the Benefits of Membrane Switch?

  • Durable, reliable, and cost effective
  • Low profile design
  • Easy to clean and wipe down
  • Ability to be completely sealed
  • Easy to incorporate graphics, textures, windows, displays, LED lighting, tactile feedback

LED Lighting

Utilizing surface mounted LEDs, Inno-Flex can incorporate back-lighting and indicators into your desired graphics and user interface.

Tactile Dome

Tactile domes provide the functional actuation you need with physical feedback in a durable and reliable package.

Embossing

Add depth to buttons using custom forming and embossing. With several different forming capabilities, Inno-Flex can provide many different embossed features including pillow, rim, dome, and multi-level.

Windows

Clear or tinted windows can be used to incorporate displays or LED indicators within a membrane switch.

Capacitive Touch

In addition to traditional membrane switch circuitry Inno-Flex can provide capacitive touch technology to incorporate innovative touch interfaces with no moving parts. Buttons, sliders, wheels, and proximity features can be easily incorporated.

Selective Textures

Selective textures and scratch-resistant hard coat coatings can be added to the overlay surface to provide unique appearances and enhance functional performance.

Polydomes

Polydomes provide a smoother and quieter alternative to metal domes. Utilizing a thermoformed and screen printed polyester film instead of metal domes, polydomes provide more flexible design options including densely spaced keypads and a wider range of actuation forces. By eliminating a circuit layer and reducing assembly costs, polydomes can provide a more cost competitive option for tactile actuation.

Fiber Optic Lighting and Light Guide Films

Inno-Flex can provide illumination, back-lighting, and lit icon indicators using fiber optic lighting and light guide films. Both technologies can provide a thin and intense lighting solution for your custom user interface.

Custom Keypads

Whether you need a standard 0-9 numerical keypad or one that has a "No Gravy" button, Inno-Flex has you covered. We take the imagination of our customers and bring it to reality to deliver exactly what they need.

Elastomeric Keypads

Obtain a rubberized look and feel with your membrane switch using elastomeric keypads. Incorporate many different appearances, textures, and lighting with this reliable and three dimensional keypad.

Value Added Assemblies

In addition to thoroughly inspecting and 100% performance testing each product, we also provide value added assembly services. We can provide you with a fully assembled and turn-key solution for your user interface so it is ready to hit the assembly line and streamline your manufacturing process. We can source and assemble sheet metal, injection molded plastics, control boards, and displays to combine with our products to provide a complete solution.
