metal dome product categories

Metal dome products are typically used in electronic devices such as keyboards, remote controls, and other types of handheld devices. 

There are several categories of metal dome products, including:

Round Metal Dome

Round Metal Dome is usually used for smaller electronic devices, Round Metal Dome is very good in feel and quality .

Oblong Metal Dome

Oblong Metal Dome is suitable for any product that uses a Round metal dome. The shape of the Oblong Metal Dome is to cut off two sides from the Round Metal Dome. When the design area is too small to place the circle, Can be replaced with an Oblong Metal Dome.

4-Legged Metal Dome

when designer reserve sufficient space & request bigger stroke travel , C-series metal dome will be prior to select to use , it’s often used in the handheld device,medical device and large banking equipment . 

Triangle Metal Dome

Under the conditions of small designed space,requested good feels & must meet bigger pressing force ,Triangle shape will be the best option , also it’s divided into w/feet or w/o feet , and it’s decide by PCB thickness & assembly method . 

Metal dome Customized

Metal dome(snap dome) can be divided into round Metal dome, 4legged Metal dome, triangle Metal dome, Oblong Metal dome and other special-shaped Metal dome. 

Single-layer metal dome

This consists of a single layer of metal dome that is used to actuate a switch or button.

Double-layer metal dome

This consists of two layers of metal domes stacked on top of each other, providing greater tactile feedback and improved longevity.

Metal dome arrays

This comprises of multiple metal domes arranged in a pattern on a substrate, providing a cost-effective solution for larger switch arrays.

Membrane switch with metal dome

This combines a thin, flexible membrane switch with a metal dome for enhanced tactile feedback.

Metal dome switch with backlighting

This is a metal dome switch with a light source placed behind it, allowing for clearer visibility in low-light conditions.
