Metal Dome Arrays, also known as metal snap domes, are momentary switch contacts that become tactile switches when used with a printed circuit board, flex circuit, or membrane. Made of stainless steel, they come in various shapes like round, four-leg, triangle, oblong, and custom.
Essentially, a Metal Dome Array is a double-sided adhesive PET array carrying the metal dome as a contact switch. Placed on a PCB PAD or membrane switch, it enhances assembly speed and precision. The structure can be single layer, double layer, rubber glue, EMI printing, or Light Guide Film (LGF).

The metal dome arrays perform important functions in membrane switches and keypads by providing most of the tactile feedback to users. In user interfaces, tactile feedback indicates the responsiveness and satisfaction felt while pressing the buttons; it is simply rewarding. These arrays are made as to be used over and over without wear and tear for effective performance in different electronics.
The manufacturers are also selective of the types of metals to be used in metal dome arrays and most times they settle for stainless steel which is ideal as it is sturdy and also conductive. The configuration on the circuit board has these domes in that different positions are made to correspond with the arrangements of the buttons on the device. When a button is pressed by the user, the metallic dome snaps down to meet the metal of the circuit below, therefore completing the circuit. Such mechanism also achieves the feedback in ergonomics but takes care of the switch electricals as well.
With the changing trends in the user interface design field, metal dome arrays are changing greatly to cope with the new requirements of electronic devices.
These arrays, which comprise dome-like metal elements attached to a printed circuit board, have developed in such designs other than the common button designs. Different shapes and configurations are being incorporated so as to enhance the feel and responsiveness of the metal dome arrays.
With the application of rapid prototyping technology, such designs, which had been considered too complex to actualize various designs are now beginning to see the light of day. In the advancement of the metal dome arrays, it is not only a functional advancement but also a visual improvement where the arrays enhance the design of the electronic devices.
Whether small and sophisticated consumer electronics for entertainment or high-class and sophisticated industrial controls, metal dome arrays tell us what is happening in the world of user interface design.
Among those technologies, metal dome arrays are widely used because of their accuracy when it comes to serving tactile elements of electronic devices. Also known as dome switches, these arrays are composed of small metal elements which are in a dome shape embedded into a circuit board and are designed to allow accurate and effective pressing of buttons.
In the course of the manufacturing process experiencing a specific actuation and tactile function requires advanced designing and electroforming of the metal domes. This accuracy helps enhance the experience of the target users either by making sure that a pleasurable feel is offered or even by preserving the electronic device for a longer duration.
As seen from a broad perspective, in use alongside other equipment, metal dome arrays tend to provide demands of use in areas such as a control panel oil, medical equipment and many other applications.
There are many time consuming and hard operations, whenever a metal dome arrays need to be manufactured so as to obtain accuracy and uniformity in the finished product. It usually starts with choosing the type of material, with stainless steel being the leading one. Stainless sheets are then further processed to improve their mechanical properties and also their corrosion resistance.
After this, special tooling is done which cuts the metal to make dome shapes. At this stage, uniformity of the domes is achieved since the level of precision is very high in this stage. Thereafter, the shaped metal domes are plated with high conductivity materials to boost their performance and usage.
Also, putting the metal dome to the PCB plate is quite a painstaking work that requires precision. The use of automated assembly systems has significantly increased production speed and reduced production errors. The distance and positioning of the domes are essential since they have to be aligned properly with the buttons of the device.
Regulatory standards are put in place for operations so that any operational variations during production are tested and corrected. This includes, but is not limited to, analysis of the feeling, testing, electrical performance and the strength on the metal dome arrays.
