How Our Tactile Metal Dome Switch Is Designed

A metal dome membrane switch is comprised of metal dome contacts mounted to printed conductors. Metal dome membrane switch arrays can be adhered to a variety of substrates including copper flex, silver flex, or rigid printed circuit boards. The electronic module is then encased inside a membrane switch assembly, all combining to make a metal dome keypad.

Metal Dome Membrane Switch Key Benefits

  • Extremely reliable contact system
  • Fast tactile response
  • Lightweight and low profile
  • Moisture resistant
  • Easy to shield

Metal Dome Membrane Switch Applications

  • Harsh environments
  • Thin form factors
  • EMI/RFI or static sensitive applications
  • Appliances
  • Medical devices
  • Industrial applications
  • Automotive

Single Source for Metal Dome Membrane Switches

ALMAX Electronic Interface Solution’s manufacturing capability includes the printed circuit boards, both rigid and flex, metal dome contact assemblies and membrane switch graphic overlays.  ALMAX is a true single-source supplier for your custom metal dome membrane switch.

Additionally, ALMAX can provide the electronic sub-components, or circuit pack, for your metal dome membrane switch.  Many of our customers are nameplate manufacturers, resellers, and other partners found within your electronics supply chain.

How Our Snap Dome Switch Works

To activate a snap dome switch, the metal dome is compressed to the substrate conductor which provides a “snap” or tactile response for the user. The tactile response coincides very closely with the moment of contact.

On a metal dome membrane switch, the activation force is determined by the construction of the metal dome.  Metal dome membrane switches allow you to design the activation force suitable for your application simply by selecting the appropriate metal dome.

Metal Dome Switches Ideal For High-Use Environments

Metal dome membrane switches are suitable for high-use environments.  The metal dome contact assembly is capable of reliability delivering a 1,000,000 or more switch actuation.

Try Our Snap Dome Switch In Harsh Environments

Our metal dome membrane switches are suitable for harsh environments since the membrane switch assembly is fully enclosed and moisture-resistant.

Metal Dome Membrane Switch For Tight-Tolerance Form-Factors

The metal dome switch construction is lightweight and can be thin, making them a suitable membrane switch choice for tight tolerance form-factors.

EMI/RFI & Static Sensitive Applications For Your Metal Dome Tactile Membrane Switch

Metal dome membrane switches are also cost-effective to shield making them an excellent choice for EMI/RFI or static sensitive applications.
