Quadrilateral Metal Dome (square metal domes) are conductive components within the metal dome switch family, featuring a square design that provides stable actuation force and excellent tactile feedback.
Manufactured by HONGMAO through precision stamping of high-quality SUS301 high-elasticity stainless steel, its intricate structure and smooth edges ensure consistent electrical conductivity even under high-frequency operation.
The square configuration not only enhances force uniformity but also facilitates adaptation to specific key profiles and mechanical layouts. We offer multiple side length specifications and contact force options, alongside OEM/ODM customisation services to meet diverse terminal device requirements.

Applications Of Quadrilateral Metal Dome
Consumer electronics are widely employed in devices requiring tactile feedback, such as remote controls, mobile phones, MP3 players, and game controllers.
Industrial and automotive electronics dome switches are suitable for high-reliability applications including automotive instrument panels and aviation equipment keyboards, withstanding extreme temperatures from -40°C to +105°C.
In medical and smart home devices, quadrilateral dome switches deliver stable operational response within medical equipment and smart home control panels.
Customer Benefits of Hongmao
Hongmao has been dedicated to the production and manufacturing of metal dome for many years. From injection molding to metal spring production, every step is strictly controlled and tested by our technical staff to ensure reliable raw materials and a complete production process.
To ensure the quality and performance of each metal dome, we have introduced advanced automated production lines and high-precision manufacturing equipment. Through highly automated production processes, we have significantly improved production efficiency and product consistency, reduced human error rates, and ensured that every customer receives high-quality products and services.
We have also established a laboratory equipped with multiple testing instruments, including life cycle testing equipment and load-displacement curve analyzers, to conduct comprehensive testing and inspection of products, ensuring that their quality and performance meet the highest standards.
Metal Dome Lifespan
1. The lifespan of dome switches is dependent upon the raw materials used, with material quality being a significant determinant of their longevity.
2. The lifespan of dome switches is influenced by their shape; circular dome switches generally exhibit the longest lifespan, followed by cross-shaped and triangular variants.
3. The lifespan of dome switches correlates with tactile feedback ratio; typically, a higher tactile feedback ratio results in a shorter lifespan.
4. The service life of dome switches correlates with their height; taller switches exhibit shorter lifespans.
5. Service life is affected by assembly practices. Switches pressed precisely at their centre demonstrate the longest lifespan, whereas assembly deviations reduce durability.
6. Lifespan is influenced by user habits; applying excessive force when pressing the switch will shorten its operational life.
