What is a Metal Dome with Rounded Corners?
Rounded corners dome corner rectangle refers to a metal dome with round shape on its corners and rectangle on its sides. It is a tactile component used in electronics, designed to provide smooth tactile feedback in user interfaces. It is officially called “oblong metal dome”, belongs to the O-series metal dome. Oblong metal domes are widely used in a variety of electronic products, commonly found in single key products, large key products and applications requiring specific shape and strength force. The O-series metal domes are usually made of stainless steel, thickness between 0.05mm and 0.1mm, hardness is generally HV480-550. According to different requirements, it can be treated with nickel plated, silver plated, gold plated and other surface treatment to improve its electrical conductivity and corrosion resistance.
What is Another Name for Oblong Metal Domes?
Oblong metal domes are often referred to as “oval domes” due to their elongated, oval-like shape. This name reflects their structural characteristics, which combine a slim profile with efficient tactile performance. These domes are also occasionally called “rectangle tactile domes” or “rectangle metal dome”, emphasizing their suitability for specific designs requiring a non-circular layout.
Types of Oblong Metal Domes
Oblong metal domes are available in various configurations to cater to specific requirements. Below are the main types:
- Oblong Metal Dome with Dimples
These domes feature small dimples on their surface, enhancing their tactile feedback. The dimples improve actuation consistency and allow better electrical contact. Ideal for high-precision applications, they are commonly used in medical devices and industrial equipment.
- Oblong Metal Dome without Dimples
Oblong metal domes without dimples feature a smooth surface, making them suitable for applications requiring uniform actuation and clean aesthetics. These domes are preferred in designs where consistent performance and simpler structural integrity are prioritized. They are commonly used in consumer electronics, automotive control systems, and standard membrane switches where tactile feedback is still essential but less intricate designs suffice.
- Customized Oblong Metal Domes
Tailored to meet unique requirements, these domes can be adjusted in size, force, and materials. They are designed for specialized applications, including custom keypads and touch interfaces. Customization allows designers to align the dome’s performance with specific project needs, ensuring seamless integration. As a leading metal dome manufacturer, Best Technology provides ready to ship (RTS) products and custom metal domes. If you are interested in, welcome to e-mail us at sales@metal-domes.com.
Features of Dome Corner Rectangle Metal Dome
The dome corner rectangle metal dome is a specialized tactile component with a rectangular shape and rounded corners. Its design combines ergonomic functionality with mechanical precision. Key features include:
- Shape and size: Oblong metal domes usually come in standard sizes and shapes to suit a variety of needs.
- Contact design: The bottom of the oblong metal dome usually has five dimples and no leg. This design makes it suitable for single key products or products where each key is separate, especially in large key products where O-series metal domes are also used.
- Application: The oblong metal dome is often used on a single key product or a product where each key is separate. Due to its pressure resistance and diverse use force, it is suitable for different product needs.
- Material and quality: Oblong metal domes are made of ultra-thin (0.05mm-0.1mm thickness) and ultra-hard (general hardness between HV480-550) stainless steel material. This material has good conduction properties, stable resilience and up to 1 million contact life.
- Surface treatment: According to the needs of different product structures and grades, oval metal domes can be nickel-plated, silver-plated, gold-plated and other surface treatments to adapt to different use environments and needs.

Why Choose Oblong Metal Domes?
The main reasons for choosing oval-shaped POTS include their space savings, suitability and cost effectiveness. ?
Because of its oval shape, they are usually used on single key products, especially for products with small area and compact wiring, such as flexible PCB (FPC)?. This design can effectively save space than circle metal dome or triangle metal dome, and due to its shape characteristics, it is easier to be compatible with double-layer stickers, further saving space.
In addition, the oblong metal dome does not have a click sound during operation, feel good, suitable for products that need a quiet operating environment. Its design is usually without feet, and can be used directly with double-layer stickers to improve the feel.
Round Corners Metal Dome Applications
Metal domes with rounded corners are widely used across industries due to their superior design and reliability. Common applications include:
- Consumer Electronics: Used in devices like gaming controllers, keyboards, and remote controls for enhanced user interaction.
- Medical Equipment: Provides precise tactile feedback in devices such as diagnostic instruments and surgical interfaces.
- Automotive Industry: Integrated into dashboards and touch-sensitive control panels for reliability under high usage.
- Industrial Tools: Durable enough for heavy-use environments like machinery interfaces.
- Telecommunications: Found in mobile devices and communication systems for consistent performance.
