Waterproof micro switches have a sealed housing that prevents water or other liquids from entering the internal components of the switch.

Yueqing, China, [December 12, 2025] — As a classic product of Yueqing Tongda Wired Electric Factory deeply rooted in the field of micro-control, the Small Push Button has become a core control component in consumer electronics, industrial control, smart devices and other fields after more than 30 years of market iteration, relying on its core characteristics of "compact size, precise triggering, and stable durability". Focusing on the "small size with great function" concept, this product takes adapting to narrow installation spaces and meeting high-frequency operation needs as its core advantages, and has long provided supporting services for well-known domestic and foreign brands, demonstrating the enterprise's technical accumulation and manufacturing strength in the micro-switch field.

If you’ve used a computer mouse, a gaming keyboard, or a compact industrial controller, you’ve probably interacted with a micro mouse switch. These tiny yet robust electromechanical components are the core of precise, responsive control, bridging the gap between physical input and electrical signals. Compact, highly sensitive, and durable, they are indispensable for all devices requiring tactile feedback.

A Long Arm Micro Switch is a compact snap-action switch with an extended lever actuator. It is designed to detect movement, position, or mechanical contact with greater flexibility than a standard plunger micro switch. Because the long lever increases the contact range and reduces the force required to trigger the switch, it is widely used in appliances, industrial equipment, automation systems, vending machines, safety devices, office equipment, and many other electromechanical products. For buyers, engineers, and sourcing teams, choosing the right long arm micro switch is not only about matching the size. Electrical rating, actuator style, operating force, terminal type, durability, installation space, and working environment all affect performance and service life. This guide explains how a long arm micro switch works, where it is used, and what to check before purchasing one.
