Metal dome array
At Shanyo, we provide a metal dome array that provides tactile feedback through membrane switches. In addition, Shanyo can also provide customized dome arrays as independent components that can be applied to circuit boards. These arrays have a variety of advantages, easy to integrate into a variety of switches, and are highly customizable.
What is a metal dome?
The metal dome is a tactile switch. They are made of stainless steel and provide tactile feedback when the switch is pressed. When integrated into the membrane switch, they form a tactile membrane switch. When applied to circuit boards, they produce a tactile touch and can be used to replace switches installed on the board.
Contrary to the name, metal domes are not necessarily circular, although circular configurations may be the most common. At Shanyo, we offer many types of metal domes, including：
• Circle
• 4 legs
• Triangle
• Rectangle
We also provide customized metal domes to meet the specific specifications of your product manufacturing plant can be customized to cut almost any shape and size.
What is a metal dome array?
The metal dome array is as its name suggests metal domes arranged in an array on a polyester film. This polyester film (although PET and other plastics are sometimes used) is lined with an adhesive. The adhesive can be removed and pasted directly to the circuit board (usually a printed circuit board or PCB).
Many of our membrane switches use metal dome arrays. Tactile membrane switches have a variety of advantages, and a metal dome is the best way to incorporate tactile into the switch.
How does the metal dome array work?
At Shanyo, we integrated a metal dome array into a membrane switch (a type of user interface). The metal dome array is located above the contact point on the flexible circuit or circuit board. When the dome is pressed, it will come into contact with the flexible circuit or circuit board to complete the circuit.
The main advantage of metal dome arrays is the tactile feedback they provide membrane switches can connect and disconnect circuits without a metal dome, these domes are the most durable way to provide users with valuable tactile feedback. Feedback.
Application of metal dome array
To understand the application of metal dome arrays, it is very important to understand how membrane switches are constructed.
The switch is constructed in the metal dome array as one layer of the membrane switch. You will also find：

The adhesive that binds the cover layer to the top circuit layer
• Circuit layer
• A gasket
• Adhesive layer on the back
• Connectors, tails, and terminals
Membrane switches may have multiple circuit layers, multiple spacers, and other layers.
These switches can be integrated into almost any electronic device, just tell a manufacturer like Shanyo the exact dimensions and tolerances you need.
Advantages of metal dome array
Broadly, there are five benefits to using metal dome arrays in membrane switches：
• They provide tactile feedback
• They are very durable (more than 1 million drives)
• They are thin and light
• They are highly customizable
• They are low in cost
By modifying the shape and density of the metal dome, we can provide greater resistance, highly obvious tactile feedback, and so on. This customization also allows us to meet the most stringent tolerance requirements. When used in combination with various materials that can be used in membrane switches (such as different gasket materials or tape), tactile membrane switches can meet almost any need.
Metal dome array use case
h2>
Metal dome arrays can be used in almost any industry, including：
• Industrial
• Electronic
• Car
• Army
• Medical
• Agriculture
• Electrical appliances
• Consumer electronics
• Transportation
• Aerospace
• Oil and gas
Although the tactile feedback provided by metal dome arrays can be used in any of these industries, the best use cases are usually consumer equipment (including consumer medical equipment), industrial, military, and medical scenarios.
Tactile provides additional and alternative feedback. For consumer medical devices, this can be used as an additional confirmation that the device has been activated, especially for users with visual or hearing impairments. For industrial, military, and medical purposes, tactile provides feedback when a large amount of audiovisual information already exists or when audiovisual feedback must be kept to a minimum.
With the high degree of customization we provide, any membrane switch can be transformed into a powerful user interface with tactile feedback. Make a product that takes into account every element of user interaction contact the universal label for a tactile dome array membrane switch!
