MEMBRANE SWITCHES FAQ'S
  • What are typical metal dome sizes?
    8 mm, 10 mm, 12 mm, 14 mm, 20 mm.


  • What is the actuation force of domes?
    Dome Force ranges from 85 grams to 700 grams.


  • Dome type, is tactile feel needed?
    Both metal (stainless steel and Gold Plated) poly domes are offered. Tactile feel is customer’s preference.


  • Which type of tactile feedback dome works best in a higher heat environment?
    Stainless Steel domes will out perform a polyester tactile dome in this situation.


  • Can you surface mount LED’S on my Membrane Switch?
    Yes. We will do it all the time with passive components.


  • Different types of Termination we offer.
    AMP, Berg, Nicomatic, Different centers and of course open contacts for ZIF application..


  • What is your “Lead Time”?
    Because we manufacture custom products our “Lead Times” are dependant on volume
    and complexity of the project. We make every effort to deliver your part the way you want it when you want it.


  • Quantities required for prototypes and production?
    1. 5 to 10 parts or lot of fixed number of parts, production qty vary from 5 to
      thousands. Due to the digital age, from approval of artwork to final part, a label or graphic overlay with EL and or membrane switches will be produced very quickly. Basically termed Fast Turn.

    2. We have all the latest design equipment and software to cater to your needs.
      Its required that we receive final approval from you before production commences. Our CAD team has the ability to create from scratch.

    including, 40,50,60,70 the higher the number the harder the rubber.


  • What kind of colors do Silicone Rubber keypads come in?
    Many different colors, we can also color match to your existing material sample.


  • Can Silicone Rubber Keypads be backlit?
    Yes. Laser etching the key tops and legends does allow backlighting to show through printed graphics.


  • What affects the life of a Rubber Keypad?
    Membrane style and durometer of the material have the most effect on a switch life. The various coating choices can increase the life of a rubber upto 20 times.
