Don't underestimate the metaldome; it's even used on airplanes!

Many people mistakenly believe it to be merely a small spring piece inside an ordinary button, unaware that it provides reliable support for everything from the remote control in their pocket, the smartphone in their hand, to the cockpit of an aircraft flying at tens of thousands of feet. In the harsh high-altitude environment, with frequent pressing operations and the imperativeness of circuit conductivity, the dome switch, despite its tiny size, upholds extremely high safety standards.

Resistant to high temperatures and vibrations, with a clear tactile feel and stable conductivity, it remains sensitive even after millions of presses. This tiny metal dome, hidden within a small space, embodies the craftsmanship of industrial manufacturing and carries the trust for device operation.
Don't underestimate any tiny existence, even the tiniest components like the tiny chip. They can take root in everyday electronic products and soar in the blue sky. With ultimate reliability, they prove that small components can also shoulder great responsibilities.
