A Metal Dome, also known as a Metal Dome Switch or Snap Dome, is a precision-engineered metal disc used to create a momentary tactile switch in electronic devices. When pressure is applied, the dome collapses with a distinct “snap,” providing tactile feedback and electrical contact between pads on a printed circuit board (PCB). These Tactile Metal Domes are critical components in user interfaces, offering reliable actuation, long life, and customizable feel. They are essential for creating responsive buttons in a vast array of applications, from consumer electronics to medical devices.
For applications demanding exceptional stability and precise registration, the four-Leg metal dome is the superior choice. Its oblong shape with rounded corners prevents lateral shift within a snap dome array, providing a defined tactile boundary that is perfect for game controllers, industrial control panels, and densely packed keypads.
When a smoother, more ergonomic actuation is desired, the Oval Metal Dome delivers. Its elongated, racetrack shape provides a gentler, rolling collapse with longer travel, which is highly suitable for rocker switches, slider interfaces, or any elongated key where a soft yet definite snap dome switch feedback is preferred.
The Round Metal Dome is the classic and most versatile metal dome switch, offering symmetrical actuation and a crisp, consistent tactile feel. Its cost-effectiveness and proven reliability make it the ideal choice for standard keypad applications such as remote controls, calculators, and keyboards.
The Triangle Metal Dome is engineered for innovative designs and space-constrained layouts. This unique shape allows for efficient use of irregular spaces and can create a distinctive tactile sensation, making it an excellent solution for specialized consumer electronics or compact devices where standard shapes are not optimal.

A: We primarily use high-quality stainless steels like SUS301 and SUS304, chosen for their superior elasticity, fatigue resistance, and corrosion resistance—key to ensuring long life and reliability for Metal Dome Switches. Other alloys are available for specific needs.
A: Absolutely. Our core service includes providing Custom Metal Dome Shapes. Whether a minor modification or a completely innovative design, our engineering team will collaborate with you from concept to prototype.
A: Force selection depends on the product type and desired user experience. Typically, 1.5N-2.5N is suitable for soft-touch consumer electronics; 2.5N-4.0N provides a more definite, crisp feedback for industrial devices or critical function keys. We provide sample kits for testing.
A: The PCB typically requires two separate circular or square contact pads. We recommend sharing your PCB layout with our engineers for review and optimization advice to ensure the best performance of your Metal Dome Switch.
A: Yes. We design and produce complete Snap Dome Arrays or Metal Dome Arrays, where multiple metal domes are precisely arranged on a single adhesive sheet or carrier tape. This facilitates high-volume automated assembly and ensures perfect alignment.
A: For standard items, our MOQ is flexible. For Custom Metal Dome Switches, the MOQ depends on design complexity and material setup. We support clients from prototyping through to mass production.
