What Is A Metal Dome？
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.
Types of Metal Domes
Custom Four Legs Tactile Metal Dome
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.
Custom Oval Tactile Metal Dome
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.
Custom Round Metal Dome
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.
Custom Triangle Metal Dome
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.
