What Is a Triangle Dome Called?
A triangular dome, commonly referred to as a triangle metal dome, is a switch component with a three-sided shape. Triangular metal dome is mainly used for thin-film switches, printed circuit boards and so on. When there is only a small space on the PCB, a smaller metal dome diameter, rebound & click feel are required, triangle series metal dome is the best choice.
Compared with other series metal domes, triangular dome can have the maximum force at the same diameter. The triangular metal dome is mostly used for special occasions, such as the need for strong press to open to avoid manual mis-operation. Generally, the size of triangle metal dome is range from 5-12mm, and the force is often between 150gf and 6,000gf. The yare especially suitable for industrial control, high pressure/high temperature and other special instrument panels or control panels.
Types of Triangular Metal Dome
This kind of triangular metal dome can be made with two feet/legs, also known as positioning leg or fixed leg. The leg width is generally 0.8mm, and there are also 0.7~1.0mm specifications. The leg length is divided into three types: short leg: 0.8mm; Middle leg: 1.5mm and long leg with 3.0mm more. With these two legs, the metal dome can be easily positioned on the PCB board, eliminating the process of welding or surface mounting.
- Triangular Dome Without Legs
This type features a flat design without any extended legs, making it ideal for compact layouts. Its low-profile nature ensures seamless integration into devices where height constraints are a priority.
- Triangular Dome with 0.8mm Legs
Designed with short 0.8mm legs, this dome provides stable contact and moderate tactile feedback. It is suitable for mid-sized devices that need consistent performance while keeping the overall height low.
- Triangular Dome with 1.5mm Legs
This type strikes a perfect balance between compactness and tactile response. The 1.5mm legs enhance contact reliability, making it a popular choice for devices requiring precise actuation.
- Triangular Dome with 3.0mm Legs
With extended 3.0mm legs, this dome offers enhanced stability and a more pronounced tactile response. It is commonly used in applications requiring durability and strong tactile feedback, such as industrial equipment.
Advantages of Triangular Dome
- Their shape fits easily into tight spaces.
- The design delivers a clear tactile response with every press.
- Made from high-grade stainless steel, they withstand extensive use.
- You can tailor their force, size, and features to your needs.
- The triangular shape ensures consistent and stable performance.
