An Oval Metal Dome is an elastic contact element with an elliptical outer contour that provides stable contact pressure through metal deformation. Its design is typically based on the major and minor axes of the ellipse, utilizing a symmetrical structure to achieve uniform force distribution. Metal springs are used in various remote controls for smartphones, digital cameras, cordless phones, electronic dictionaries, healthcare devices, and other applications.
Oval Metal Dome Features
Symmetry: The elliptical shape provides uniform stress distribution, reducing the risk of single-point fatigue.
Contact characteristics:
Single-point contact: Center protrusion design for high-precision conduction (such as micro switches).
Multi-point contact: Multiple contact points distributed around the elliptical edge for enhanced reliability (such as battery connectors).
Deformation Mode: When pressed, the ellipse undergoes elastic bending along the long axis, with the short axis providing support.
Customization Services: Being a spring manufacturer, full customization services that include size, force, coating, and packaging are offered according to your PCB layout and feel requirements (operating force and travel) as well as appearance.
Oblong Snap Dome Can Be Divided Into Below 2 Types :
1. Non-recessed type: No series numbering
2. Central single, triple, quadruple, or quintuple indentation type
Occasionally, a central aperture may be present under specific circumstances
Oblong metal domes: Suitable for virtually all products accommodating circular metal push buttons. Their shape is formed by trimming the sides of a circular button. When the design area is too small to accommodate a circular button, an oval button may be selected as an alternative.
