Product Description

The G304-K series Waterproof Sub-Miniature Micro Switch is a waterproof micro switch designed for confined spaces and humid environments. It is widely used in home appliances, particularly suitable for functions such as door detection, button feedback, and operating status switching. Its compact structure, combined with a left-facing fork-shaped terminal design, allows for more flexible installation and wiring. With a maximum operating force of 150gf, it strikes a good balance between light operation and stable triggering, providing reliable input signal control for various home appliances. Even after long-term use, the switch maintains its agile response and withstands the challenges of dust, moisture, and temperature fluctuations in complex home environments.

In automotive electronic systems, this sealed micro switch also plays a crucial role, suitable for low-current control scenarios such as in-vehicle buttons, door mechanism detection, and cabin micro-actuators. Its high sealing performance allows the switch to operate stably in environments with vibration, temperature variations, dust, and occasional moisture, ensuring the accuracy of automotive electronic signal transmission. The left-facing fork-shaped terminal design not only improves wiring harness layout efficiency but also facilitates integration into compact electronic modules, meeting the reliability, durability, and miniaturization requirements of modern automobiles.

Notably, the G304-K series boasts an IP67 waterproof and dustproof rating, making it a true IP67 micro switch. This ensures excellent sealing performance in outdoor environments, under fluctuating temperatures, and high humidity conditions. Its operating temperature range covers -40℃ to +85℃, humidity conditions below 85%RH, and a mechanical life of 300,000 cycles. It maintains stable contact performance even under high-frequency operation, fully demonstrating its high reliability. With its durable structure and high environmental adaptability, it is suitable not only for home appliances but also for automotive electronics where stability requirements are more stringent.

Overall, the Waterproof Sub-Miniature Micro Switch G304-K series is a high-performance, sealed micro switch meticulously designed by a micro switch manufacturer. Integrating miniaturized structure, long lifespan, high sealing performance, and flexible terminal design, it provides a safe, stable, and high-quality input control solution for modern home appliances and automotive electronic systems, demonstrating consistently reliable performance in a variety of complex application environments.
