Pushing the Limits: Switch Series Ultra-Thin Waterproof Micro Switch Achieves 10 Million Clicks at Just 3mm Thickness
Nov,05,2025

Shenzhen Topway New Energy Co.,Ltd. are a leading manufacturer of electronic components, today launched the revolutionary Switch Series of ultra-thin waterproof micro switches. This product features a groundbreaking design that successfully achieves an exceptional mechanical life of 10 million clicks within an ultra-slim profile of just 3 millimeters, setting a new industry benchmark for devices demanding slimness and high reliability.

As markets for wearable devices, precision medical equipment, high-end consumer electronics, and ultra-thin appliances rapidly evolve, internal space has become a premium resource. Traditional micro switches often force a trade-off between lifespan and size, being either too bulky or too fragile. The introduction of the Switch Series perfectly resolves this core dilemma.

This technological breakthrough is made possible by three key innovations:

  1. Innovative Reed Structure and Materials Science: The switch incorporates a precision reed structure made from high-performance specialty alloys. Millions of dynamic simulations via computer-aided engineering optimized its stress distribution, ensuring optimal force and rebound with every actuation. The material's superior fatigue resistance is the fundamental guarantee for withstanding tens of millions of click cycles without failure.

  2. Integrated Miniaturization and Robustness Design: Despite its miniature size, the switch's housing and internal use high-strength engineering plastics and metal composites. This design not only reduces overall weight but also, through ingenious snap-fit and support structures, ensures the stability and alignment of internal components during frequent operation, effectively preventing failures due to deformation.

  3. Reliable Ultra-Thin Waterproof Sealing Technology: To achieve effective waterproofing (typically up to IP67 or higher) at a 3mm thickness, the Switch Series employs exclusively developed laser welding technology and an ultra-thin flexible sealing gasket. This sealing solution creates a robust barrier within an extremely confined space, preventing the ingress of moisture, dust, and contaminants, ensuring stable performance even in harsh environments.

"We are committed to solving our customers' most critical design challenges," said a Product Manager at Shenzhen Topway New Energy Co.,Ltd. "The launch of the Switch Series ultra-thin waterproof switch means engineers no longer have to compromise between product thickness, lifespan, and reliability. It is particularly suited for cutting-edge applications like side buttons on foldable smartphones, hidden buttons on smartwatches, and precision controls in portable medical devices."

The introduction of the Switch Series signifies greater design freedom and higher reliability for electronic devices and is poised to drive the next wave of development in slim electronics.
