T-series snap domes(metal domes) a triangle-shaped metal domes that is designed for mounting on single or double-sided printed circuit boards, flex circuits, and membranes, where a Via is run through the circuit board.

Applications requiring a good click feeling but limited to narrow space, such as small, hand-held devices, are a perfect fit with our Triangle series metal domes. On the same diameter, we can get the biggest force from the triangle dome. The Trip force can reach up to 540g, so this triangle tactile dome can be used as a heavy force control switch to avoid careless operation.
Most of the triangle dome has two legs (feet) that can be inserted into the hole of the circuit board so that it can be fixed on the circuit without any adhesive tape and can be used in high temperatures. Sometimes people named it a “metal dome with legs”.

The T-series snap domes, available in diameters ranging from 4mm to 12mm, offer a wide range of actuation forces from 100g to 5000g. One significant advantage of the T-series domes, especially within the same diameter, is their ability to achieve higher actuation forces, often exceeding 600 grams. This makes them particularly suitable for applications that require robust tactile feedback and strong actuation force within compact designs.

We don’t recommend soldering its leg on a circuit which reduces the life cycle and clicking feeling. You can also visit our blog for more information such as how to assemble a triangle dome and other technology about triangle metal domes.

To complement our diverse variety of domes, Shanyo offers T-Series metal domes with various features.

The T-series snap domes are further categorized based on their structural design, specifically the presence and size of legs. Here are the four variations:

1. NT-series: Without legs

2. ST-series: With two short legs measuring 0.8mm in width and 0.8mm in length

3. MT-series: With two middle legs measuring 0.8mm in width and 1.5mm in length

4. LT-series: With two long legs measuring 0.8mm in width and 3.0mm in length

These structural differences allow for varied mounting and performance characteristics, providing flexibility in how the domes are integrated into different devices and applications.

T-Series tactile snap domes are an inexpensive alternative for projects with relaxed tolerance requirements and cost constraints. Contact Shanyo to see if T-Series domes may be right for your application.

Snap Dome Structure

Metal-Dome-Structure

Snap Dome of pot flakes

Snap Dome as a metal dome. Compared with traditional silicone buttons, conductive film has a better feel and longer life. It can also indirectly improve the production of various types of switches using conductive film. efficiency. The metal spring on the dome button is located on the conductive part of the PCB (mostly located above the gold finger on the circuit board). When pressed, the center point of the spring is concave and contacts the circuit on the PCB, thus forming a circuit. , the current passes through, and the entire product can work normally. This is how it works.

Snap Dome The structure of the product is categorized:

(1) Single layer structure
This is the simplest structure at the beginning, the metal shrapnel is located underneath the Mylar (a layer of PET with adhesive), and there are ventilation holes to ensure the basic feel and use.

Single-Layer-Mylar-Metal-Dome

(2) Double-layer structure
A single layer of the conductive film is different, it has a layer of Spacer (spacer), shrapnel better paste, and Mylar adhesive on top, and maintains good contact with the circuit board, with a better feel (some similar to the membrane switch ‘bulge’) In addition, the double-layer structure of the conductive film on the ventilation slots can be more effective in preventing the PET layer by the In addition, the ventilation slots on the double-layer structure of the conductive film can more effectively prevent the PET layer from being scratched by the blade burrs of the shrapnel, etc., and can also prevent dust from entering the PET layer.

FAQs

Frequently Asked Questions

Q: What is a snap dome?
  • Metal snap domes (tactile metal domes) are made of stainless steel and are momentary switch contacts. Combined with printed circuit boards (PCBs), flexible circuits, or membranes, they become normally-open tactile dome switch.

    This metal dome has the following characteristics and advantages:

    I. Material characteristics

    The stainless steel material gives the metal dome good durability and stability. It can withstand multiple presses without being easily deformed, ensuring the long-term reliability of the switch. At the same time, stainless steel has good electrical conductivity, which can effectively transmit electrical signals to ensure the normal operation of the switch.

    Second, the working principle

    When an external force is applied to the PCB, flexible circuit, or film combined with the metal dome, the metal dome will deform, thus realizing the closure of the circuit. Once the external force disappears, the metal dome will quickly return to its original state, breaking the circuit and forming a normally open state. This instantaneous switching action provides clear tactile feedback, allowing the user to perceive the success of the operation.

    III. Application Areas

    1. Electronics: Widely used in a variety of electronic devices such as cell phones, tablet PCs, remote controls, etc., providing users with a convenient operating experience.
    2. Industrial control: In industrial automation equipment, a dom switch can be used to control the start and stop of various functions.
    3. medical equipment: due to its reliability and accuracy, tactile dome switch are also suitable for various operation controls in medical equipment.

    In conclusion, metal snap domes play a key role as an important switching component in electronics and related fields. Its high performance and reliability make it ideal for many product designs.

Q: What is the approximate lifespan of the Snap Dome?
  • The service life of a metal dome is affected by a variety of factors, such as dome material, shape, size, production process, and the environment in which it is used.

    Generally speaking, the life span of the metal dome varies greatly in China. The life span of a cross-shaped dome is usually around 200,000 to 300,000 times; the life span of a round snap dome, such as 4c, c5 and other smaller domes, is about 700,000 to 800,000 times in China. And can reach 500,000 to 1 million times the life of the dome is relatively small.

    However, with some metal domes made of special technology or high-quality materials, their life may be longer. For example, in the metal dome used in some mouse axle bodies, after optimized design and material selection, the theoretical service life can reach 80 million times.

    If the metal dome is frequently subjected to high-intensity pressure, intense friction, or in poor environmental conditions (such as high temperature, high humidity, etc.), its life span may be shortened accordingly.

    In order to extend the service life of metal domes, in the process of product design and use, you can try to choose reliable quality domes, and avoid excessive use or use of related products in extreme environments. At the same time, reasonable design and manufacturing process can also help to improve the life and performance stability of metal dome.

Q: How do snap domes work?
  • Snap domes work through a combination of mechanical and electrical principles. Here’s how they operate:

    Mechanical Action:

    When at rest, the snap dome is in a convex shape. As a force is applied to its center, it starts to deform. The metal of the snap dome is resilient and has a certain amount of springiness. As the force increases, the dome gradually flattens out.

    At a certain point, known as the “snap point,” the dome suddenly inverts and snaps into a concave shape. This rapid inversion creates a distinct tactile feedback, often described as a click or a pop. This tactile sensation is useful in applications where users need confirmation of an action, such as pressing a button on a keypad or a switch.

    Electrical Function:

    Snap domes are often used in conjunction with a printed circuit board (PCB), flex circuit, or membrane. When the snap dome is in its un-actuated state (convex), it is electrically open, meaning there is no electrical connection between the contacts it is designed to connect.

    However, when the dome snaps into its concave state due to the applied force, it makes contact with the underlying electrical contacts on the PCB or other substrate. This creates an electrical connection, allowing current to flow through the circuit. Once the force is removed, the snap dome returns to its original convex shape, breaking the electrical connection again.

    In summary, snap domes work by mechanically snapping from a convex to a concave shape when pressed, providing tactile feedback, and simultaneously creating or breaking an electrical connection to control the flow of electricity in a circuit.
