Custom Membrane Switches and Keypads

Membrane switches are an essential component of products ranging from household appliances to sophisticated medical equipment. Achieving the right design depends on the technology and manufacturing quality provided by a custom membrane switch manufacturer.

Dyna-Graphics Corporation designs and manufactures ready-to-use custom membrane switches based on your specifications. Our company has experience working with clients across a range of industries, from agriculture to medical, and will work with you to devise the perfect custom assembly solution.

Any custom assembly design your membrane switch requires, no matter how simple or complex, can be built to your exact specifications. We focus on small- to medium-volume membrane switch production and can work with customer-supplied casings or manufacture them to order.

Our Custom Membrane Switch Technology and Options

As a turnkey membrane switch manufacturer, Dyna-Graphics has wide-ranging production capabilities. We can produce a broad array of custom membrane switch panels, as well as specialty models for unique or challenging applications.

Our membrane switch capabilities include:

High-Quality Membrane Keypads with the Functionalities You Need

We bring all the necessary parts and components together to create a finished product that meets your unique requirements: the membrane switch itself, a PCB as part of the assembly, a custom panel to support the switch and PCB, the exterior casing, LED lights, backlightingwaterproofing, and LCD screens, and more.

Depending on your need for backlighting and/or front panel illumination, Dyna-Graphics can produce custom membrane switch panels with embedded LEDs.

We can also produce rugged, extra-durable membrane switch panels. These switches are ideal for applications where the membrane switch may be subject to hard use or abuse due to harsh environmental conditions or work environments.

K-Motion Membrane Switch Panels

Our K-motion membrane keypads feature conductive silver pad areas separated by screened dielectric spacers. This design is ideal for environments where low actuation forces are needed. Designed for superior durability, these membrane switches show no damage after actuation testing of 5 million cycles with 10 mil Velvet Lexan overlay.

Additional features include:

  • Dielectrically shielded to withstand voltage of 500 Volts DC for up to 120 seconds
  • Heat-stabilized 5 mil polyester material with 3M 200MP or 300MP adhesives
  • Silver-filled conductors with ultraviolet (UV) cured dielectric application
Full assembly including membrane switch, LCD, PCB, box and cable

Non-Tactile Membrane Switch Panels

Non-tactile membrane switches do not provide any sort of snap action when a user presses the keypad. This simple and cost-effective design provides reliable function and long cycle life for use in a range of applications. We cycle tested our non-tactile membrane switches well over five million times to ensure high reliability and durability.

Features include:

  • Micro-travel action with actuation forces in the 4- to 8-ounce range.
  • Embedded LEDs can be attached to the conductive silver traces for display areas and lighted windows.
