What Is Four Legs Tactile Metal Dome Switch ？
The four legs tactile metal dome switch is a precision elastic component made of stainless steel SUS301/304 with a thickness range of 0.05mm–0.1mm. This metal dome switch features a unique four-leg support structure that enables reliable switching functionality – when pressed, the center point contacts the PCB circuit to establish conduction, then automatically rebounds using material elasticity when released.
This dome switch is renowned for its maximum operating travel, relatively high actuation force, and crisp audible feedback. The four-leg support structure ensures exceptional stability, with a service life exceeding 500,000 cycles. Its working principle is based on the dome center deforming under pressure to contact the PCB circuit, completing the “press-conduct-release-disconnect” switching cycle.
As a crucial member of the metal dome family, the four legs structure offers longer travel and clearer tactile feedback compared to circular and triangular domes. It is typically supplied as individual domes or pre-mounted on PET films (as “dome switch stickers”), supporting customized sizes, actuation forces, and surface treatments to meet specific application requirements.

자주 묻는 질문
What are the main differences between four legs tactile metal dome switches and circular/triangular ones?
A: 4개의 다리 메탈 돔 스위치는 최대 이동거리, 높은 작동력, 선명한 청각적 피드백으로 뛰어난 지지 안정성을 제공합니다. 원형 돔은 트래블이 최소화되고 소리가 약하며, 삼각형 돔은 그 중간에 속하지만 일반적으로 네 다리 돔보다 수명이 짧습니다.
Can the four legs metal dome switch really achieve 500,000 cycles?
Yes. four legs Metal Domes made from imported SUS301/304 stainless steel with strictly controlled manufacturing processes can reliably achieve over 500,000 cycles under standard pressing conditions.
Can Metal Dome switches be customized with different surface platings?
Absolutely. Shanyo supports various surface treatments, including gold plating (0.15–0.2μm), silver plating, and nickel plating. Gold plating suits high-conductivity applications, while nickel plating focuses more on corrosion resistance.
How to select the appropriate dome switch? What specifications do you recommend?
Choose based on application:
Remote controls/Small appliances: 7mm, 8.4mm with 150gf–200gf force
Industrial panels/Security devices: 12.2mm, 14mm with 200gf–280gf force
Medical/Automotive equipment: Recommend gold plating with verification of -30℃~85℃ temperature adaptability
What precautions should be taken during dome switch assembly?
Ensure the dome center aligns with PCB contact points with ≤0.1mm deviation
