Membrane Keyboards Types, Uses, Features and Benefits
SMD Dome Switch is a type of new metal dome package which designed to be soldered on PCB/FPC/MCPCB, or any other circuits, by directly SMT/SMD reflow soldering technology.
Switch Technology for Military and Aerospace Bezel Assemblies
Domes are pre-loaded in the exact positions you require so that multiple domes can be placed with one application. The adhesive used allows the domes to flex and maintain the dome switch's feel and function. Adhesive Tape Materials Adhesive is a common method to hold metal domes in place.

On actuation, the Clik Dome ( Snap Dome ) is deflected over the contact point between switch circuit layers (membrane switch type design), or between concentric pad layouts (PTH-PCB design and many flexible circuit designs). Actuation then completes the electrical circuit, and provides a high tactile response.

metal dome switches secured to a PCB with tape 3. How do I secure the metal domes to my PCB, membrane, or flex circuit? Metal dome switches are secured using pressure-sensitive adhesive tape or can be soldered down by hand or with an SMT machine in a solder reflow process, depending on the style of the dome. Several standard adhesive material.

Metal dome is an important part of the dome switch PCB. They are momentary switch contacts that become normally-open tactile metal dome switches when used in conjunction with a printed circuit board (PCB). PCB is also known as printed circuit boards because it is made by electronic printing.
PCB Metal Dome Membrane Switch / Non Tactile Custom Membrane Switches
Thanks to the technology and process of 4-legged Switch'Air™ domes patented by Nicomatic (cushion of air between metal domes), domes do not stick to each other any longer. The placement of components on flexible or rigid circuits becomes more reliable in Pick & Place mode and allows to increase productivity per placed dome. It is not necessary to use a multi-layer PCB or PCB piercing.

These switch contacts are designed for mounting on double sided PCBs, FPC circuits, and silver flex membranes. Oblong metal domes are perfect for applications that require a low profile switch on an overly populated circuit board. They also may be used in long, narrow spaces that cannot accommodate other domes. Custom Metal Domes

The mechanics of dome-array switches are relatively simple. Dome-array switches have two conductive contacts. One of the contacts is located on the bottom of the key. The other contact is located on the PCB below the key. Pressing a key will allow the two contacts to meet so that it opens or closes a circuit. Benefits of Choosing Dome-Array.

An Integrated SMD Switch Solution Engineered for automation, the solder dome features two tabs that allow it to be surface-mounted directly to the circuit-without impacting performance. Like standard metal domes, the solder dome is a normally open momentary contact that provides a crisp tactile feel.
