A metal dome array & dome sheet ( dome array) is a kind of double sided adhesive PET array (sheet) that carries metal dome as contact switch to put on PCB PAD or membrane switch, so that accelerate assembly speed and precision. We divided them based on structure into following types: Single layer Double layer Rubber Glue EMI printing

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.

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.
Metal dome PCB Membrane Switch
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.
High Quality Tactile Metal Dome Switch, Membrane Switch for Remote Control China Dome Metal
Tactile switches are actuated by pressing an actuator on a metallic dome that makes contact to the terminals over-molded in the plastic body. They are simple and efficient in their functionality, but very versatile in their application areas.
IP67 Rated Dome Pushbutton Switch Red (Jaycar SP0657) Little Bird
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

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.

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.
