Metal Domes

The Memcon range of snap metal domes have been developed for use in membrane switch and mechanical switch assemblies.

Our tactile metal domes and snap metal dome arrays are incorporated into a wide range of applications including mobile phones, test equipment, flexible circuits, domestic appliances, switches and keyboards to name but a few.

When manufacturing tactile metal domes we use only the highest quality stainless steel produced in the Unites States of America or Japan thereby ensuring that we have a consistent level of quality from batch to batch.

A variety of plating is available to meet our customers needs including silver and gold plating.

Custom Metal Dome Arrays

Custom Metal Dome Arrays

Custom Metal Dome Arrays

Dome Arrays assemblies have become common practise with many membrane switch/circuit manufacturers who are utilising them to help take cost out and speed up assembly times. As the operator places one large dome array in one application instead of each dome individually, production time is reduced dramatically. Quality improvements and benefits can also be enjoyed with the reduction in placement errors and “Double Doming.”

Dome arrays are also a great way of enhancing the tactile feel of a rubber keymat or simply sticking directly to a pcb with an overlay to create a tactile switch effect.

We are able to offer an extensive range of dome array designs from simple single layer PET dome arrays to those requiring spacers and EMI shielding layers.

Construction methods

Single Layer Dome Array
One of the most original styles of dome array where the domes are placed on a layer of PET film with an adhesive layer.

Holes or kiss cuts are required around the dome to assist with the breathing of the dome there by maintaining a good tactile effect.

An ideal low cost solution to stick straight to the PCB.


EMI Single/Double Layer Dome Array
Here the construction method is similar to the two above but in addition a layer of silver or carbon paste is printed to provide EMI/RFI shielding to the top of the PET film.

Double Layer with Rubber Glue
Utilising the construction options above we can add an additional layer of Rubber Glue which is ideal for use with rubber keypads providing enhanced adhesion characteristics.

Double Layer Dome Array
With this type of construction a spacer layer is incorporated into the assembly.

Venting for the metal domes to breath can be incorporated into the spacer layer if required.

Varying thickness and materials can be utilised for the spacer material.

Dome Arrays can be manufactured as simply as say one or two domes on a polyester backing to large panels which may incorporate a large number of domes in a pattern to suit a custom application. Different size/types of domes can be incorporated into the array design.

A dimensioned drawing with construction requirements along with dome sizes and parameters and yearly quantities are needed to make an offer. Budgetary pricing can be provided from hand sketches if required.
