Legged Design: A Secure and Resilient Solution

The legged design features two sturdy legs, or "feet," engineered for effortless insertion into holes on the circuit board. Unlike traditional attachment methods, this design eliminates the need for adhesive tape, ensuring a robust and reliable fixation. The legs firmly anchor the domes in place, preventing any unwanted movement or displacement during operation.

In addition to their secure attachment, these legged metal domes are built to withstand high temperatures. This heat - resistant construction makes them an ideal choice for applications in environments where elevated temperatures are a concern. Whether it's in automotive electronics, industrial control systems, or other heat - intensive settings, these domes maintain their integrity and functionality.

Thanks to their distinctive two - legged structure and heat - resistant properties, these metal domes have earned the apt nickname "metal domes with legs." Their unique design combines ease of installation, secure attachment, and thermal resilience, making them a versatile and reliable component in a wide range of electronic applications.

The T-series snap domes are categorized into four types:

01.

NT-series: No legs

Some other T-Series domes do not have legs. They are typically for those who use tape or other methods to secure the dome to a circuit board or film. This legless design is uniquely suited to meet the diverse assembly requirements of different electronic devices in a number of specific mounting needs and space layouts.

02.

ST-series: Two short legs (0.8 mm x 0.8 mm)

Snap domes in this series feature two short legs, each measuring 0.8mm in width and 0.8mm in length. These short legs are designed to be inserted into corresponding holes on the circuit board, providing a secure mechanical attachment without the need for adhesive. The ST-series is suitable for applications where a compact size and secure fixation are important.

03.

MT-series: Two medium legs (0.8 mm x 1.5 mm)

This series includes snap domes with two middle legs. The legs in the MT-series are 0.8mm wide and 1.5mm long. These dimensions offer a balance between secure attachment and stability. The MT-series is commonly used in applications where moderate force and durability are required.

04.

LT-series: Two long legs (0.8 mm x 3.0 mm)

Snap domes in the LT-series feature two long legs, each measuring 0.8mm in width and 3.0mm in length. The longer legs provide a more robust mechanical attachment, making them suitable for applications where the snap dome may be subjected to higher forces or where additional stability is needed. The LT-series is often chosen for devices that require a strong tactile response and durability.

T - series metal domes come in diameters from 4 to 12mm and actuation forces between 100 and 5000g. For the same diameter, forces often go over 600g, making them great for tough applications and improving user experience.

There are two types: legged and non - legged. Legged domes can be inserted into holes on the circuit board and resist heat. Non - legged domes need to be attached with tape.

The ACH series tactile rings offer options based on leg length and type. This helps designers choose the right model for different installation needs and required actuation forces.

Metal Dome Types and Their Uses

Round Metal Domes

Round metal domes are perfect for compact electronics. Their circular shape takes up little space, making them ideal for devices with limited room, like mobile phones. They offer a great balance between tactile feedback and strength, and can withstand millions of presses. This durability makes them a top choice for control panels of key equipment and other high - use applications.

Oblong Metal Domes

Oblong metal domes, including T - series, come in various specs and with or without legs. Oval and rectangular ones work well as alternatives to round domes in certain designs. Their shape gives them a good tactile feel, and they can be used in many different scenarios, adapting to different installation needs.

Four - Leg Series Metal Domes

Four - leg metal domes stand out with their long stroke and distinct click sound when pressed. They're suitable for situations where there's plenty of space on the PCB, and the buttons need to be large with a significant travel distance. You'll often find them in handheld devices, medical equipment, and large banking machines.

Triangular Metal Domes

When space is tight but you still need a good tactile response and strong pressing force, triangular metal domes are the way to go. They come in two versions: with or without legs. You can choose the right one based on the PCB board thickness and the assembly process.

Special - Shaped Custom Metal Domes

Metal domes are mainly grouped into round, oval, triangular, and four - leg types. Any other shape is considered custom. We can make all kinds of metal domes to order. Whether you need a specific shape, size, or strength, we can create the perfect custom - shaped metal dome for you.
