Custom Membrane Switches

Marking Systems, Inc. manufactures a full line of Membrane Switches ranging from silver flex, copper flex, capacitive touch, dura switch, resistive touch, rigid PCB and rubber keypads. Lighting features include fiber optics, light guide films, embedded LED's and electroluminescent. MSI's engineering team can also help with additional features such as EMI/RFI shielding and sealing technologies such as IP69 designed for total submersion. Whether you need help with new design or trouble shooting our team of membrane engineers stands ready to help.

The fabrication services provided by Marking Systems, Inc. include all aspects of product design and manufacturing for custom membrane switches.

We produce:

  • Keypads
  • Silver flex circuits
  • Copper flex circuits
  • Tactile and non-tactile switches
  • Silver flex/copper flex circuit options
  • PCB switches
  • Rubberized keypads
  • Digital touch screens

Offering a variety of custom options including:

  • Stainless steel domes
  • Poly-domes
  • PC board mounted switches
  • PEM inserts
  • Automatic SMD LED placement
  • Sealed NEMA 4 rated construction
  • Sub panel assemblies
  • Lighting Options:
    • LED
    • Light Guide Film
    • Electroluminescence (EL)
    • Fiber Optics

Our membrane switches have an actuation life of 1,000,000 to 2,000,000 cycles. We have backlighting options consisting of: LED, light guide film, electro luminescence (EL), and fiber optics. We can fabricate these switches along with graphic overlay made from various polyesters and polycarbonates. Our membranes can withstand temperatures ranging from -20°C to 75°C. Electrical specifications include ESD / RFI shielding options, through-hole or two-sided flex circuits, 100 mA at 28 VDC max and maximum load 1.5 VA nominal.
