Center Hole Metal Domes

performance of metal domes 

One of the significant advantages of TC-Series domes is their ability to perform consistently, even if the actuator is located off-center. Traditional metal domes often experience variations in performance when the actuation force is applied off-center, leading to inconsistent tactile feedback. The TC-Series domes, however, overcome this limitation, providing a reliable and uniform response, which is crucial for applications requiring precise and consistent actuation.

wide application of metal domes 

Metal domes, including the TC-Series, play a vital role in numerous applications. These include:

1. Single Key Metal Dome : The TC-Series domes are ideal for single key applications where reliable tactile feedback and consistent performance are essential. Their innovative design ensures that each key press is registered accurately, enhancing user experience.

2. Metal Sheet Metal Dome  Fabricators: For fabricators specializing in metal sheet domes, the TC-Series offers a superior option. The reverse dimple design allows for easy integration and consistent performance, making them a preferred choice for fabricators

3. General Use in Electronic Devices: TC-Series domes are widely used in electronic devices, such as remote controls, membrane switches, and keypads. Their reliable performance ensures that these devices operate efficiently and effectively.

The Role of Metal Domes

Metal domes are crucial components in many electronic devices, providing the necessary tactile feedback that users rely on. They serve as the primary interface between the user and the device, ensuring that each input is accurately registered. The TC-Series domes, with their innovative design and consistent performance, elevate the functionality of these devices, making them more reliable and user-friendly.

In conclusion, the TC-Series domes represent a significant advancement in metal dome technology. Their unique reverse dimple design, consistent performance, and reliability make them an ideal choice for a wide range of applications. Whether used in single key applications, by metal dome fabricators, or in various electronic devices, the TC-Series domes play a crucial role in enhancing user experience and device functionality.

custom metal dome working principle

 

The snap dome is also commonly known as a metal dome or tactile metal dome switch. Compared with traditional silicone keys, the conductive film has a better feel and longer life. It can also indirectly improve the production efficiency of various types of switches using conductive films. The metal snap domes on the snap dome switch are located on the PCB board's conductive part (mostly above the gold finger on the circuit board). When pressed, the center point of the dome is concave and contacts the circuit on the PCB, thus forming a loop, and the current passes through, so that the entire product can work normally. This is its working principle.

Special-shaped custom

Round metal dome: The special structure of the round shape has the advantage (a small footprint), so it is mainly used in electronic devices with small spaces. At the same time, it can take into account the rebound and strength of the hand feel, and at the same time, it is more stringent in places where the product life is required (more than one million times), such as mobile phones, control panels of key equipment, etc.

Oblong metal domes: They can be used in almost all places where a round dome is used. Its shape is a regular waist circle formed by cutting off a part of the two sides of the round dome. When the space in one direction of the design is small and the round dome cannot be placed, it can play its specialty. Oblong metal domes (Oval metal domes, rectangle metal dome) also have an excellent hand feel.

Four leg series metal domes: refers to a dome with four legs, also known as a four-leg dome. It is a metal dome with a relatively large stroke and a clear sound when operated. This series of domes can be used when there is more space on the PCB, the button position is large, and the travel requirement is large. It is generally used for handheld devices, medical equipment, and large bank equipment.

Triangular metal dome: When there is a small space that can only hold a small dome and at the same time needs to have a good feel and must meet the requirements of greater pressing force, the triangular metal dome is the best choice; it is also divided into two types with feet and without feet, which is selected by the thickness of the PCB board and the assembly process.

Special-shaped custom metal dome: Metal domes are mainly divided into round, oval, triangular, and Four leg series. Other special ones are collectively referred to as special-shaped metal domes. Metal domes are custom-made products. All kinds of metal domes can be customized according to requirements. In addition, special-shaped metal domes can be customized according to shape, size, strength, and other requirements. If you have any needs, please contact us at Shanyo.
