T-series snap domes

• 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.

• 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.

• 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.
