Metal Domes Manufacturer
F-Series domes have four legs and can achieve high actuation forces and tactile relative to their size. They are available in a wide variety of sizes and actuation forces.
Their crisp tactile feel, wide variety of styles, and versatility of use make the F-Series domes some of Shanyo’s most popular designs. Four-legged domes can be mounted to a wide variety of switching surfaces, including single or double-sided printed circuit boards, flex circuits, and membrane switch panels.
Four-leg series metal domes are also called cross-metal domes. The most obvious difference from other shrapnel is that it has four legs. Compared with the Triangle Dome, it has a longer life cycle; its normal life span is greater than or equal to 1 million times. Widely used in single-sided or double-sided printed circuit boards, flex circuits, and membrane switches. Under the same diameter, force, and clicking ratio, its height is higher than other domes, and its price is also higher than other domes.
The Four-leg series metal dome size is 5mm to 20mm, and the triggering force range is 125-500gf. Resilience, stroke, etc., can be adjusted at any time according to customer requirements.
We can pack them in normal bulk or tape them one by one on the array so they can be easily peeled off and placed on key locations on the keyboard, FPC, and PCB. According to whether the dome has a dimple, it can be divided into.
Metal Dome Structure

Snap Dome of pot flakes
Snap Dome as a metal dome. Compared with traditional silicone buttons, conductive film has a better feel and longer life. It can also indirectly improve the production of various types of switches using conductive film. efficiency. The metal spring on the dome button is located on the conductive part of the PCB (mostly located above the gold finger on the circuit board). When pressed, the center point of the spring is concave and contacts the circuit on the PCB, thus forming a circuit. , the current passes through, and the entire product can work normally. This is how it works.

Classification of Adhesive for Metal Domes:
Transparency: Better alignment
- White: generally used with light guides (reflective)
- Black: generally used to block out light (obscuring the content)
- Yellow: it belongs to high-temperature resistant material (can exceed SMT high-temperature effect for a short time)
- Silver screen: grounding anti-static effect Transparency: Better alignment
- White: generally used with light guides (reflective)
