Product Description
 

The G304R Series Sealed Sub-Miniature Micro Switch is a compact and highly waterproof micro switch, ideal for precision control applications in home appliances. Its internal highly reliable sliding clip structure maintains stable contact performance even under a maximum actuation force of 150gf, ensuring no jitter or accidental touches under light loads and frequent operation.


As a sealed micro switch, it maintains good responsiveness over a wide operating temperature range of -40℃ to +85℃ and ensures stable insulation and conduction under a maximum humidity of 95%RH (+5℃ to +35℃). In modern home appliances such as smart door locks, kitchen appliance safety sensor modules, and small motor feedback systems, the G304R series provides reliable control and detection support with its precise dimensions and stable output.


In automotive electronics applications, the G304R series, as an IP68 micro switch meeting stringent environmental requirements, maintains excellent performance even after prolonged exposure to moisture, rain, dust, vibration, and even mud and sand. Its IP68 waterproof and dustproof design makes it ideal for automotive electronic systems with extremely high sealing requirements, such as door lock detection modules, pedal position feedback, and light-load signal sensing within the vehicle. Combined with its 10~55Hz, 1.5mm dual-amplitude vibration resistance, this waterproof micro switch maintains contact stability even under high-speed driving, vehicle vibration, or harsh road conditions, preventing malfunctions or signal loss due to mechanical vibration, thus effectively improving vehicle safety and control accuracy.


As a highly reliable sealed micro switch meticulously designed by the micro switch manufacturer, the G304R series not only features reinforced structure and high sealing performance, but its compact design also allows for flexible installation in confined spaces, making it suitable for various home appliances and automotive electronic control modules. Its IP68 sealing performance further ensures continuous and stable operation in extreme environments, providing users with reliable feedback signals in high humidity, high dust, large temperature differences, and strong vibration environments. This high-performance design also makes it an ideal component for a wide range of detection, limit, and status verification systems.

Application
 
As a compact, highly sealed, waterproof micro switch, it is widely used in home appliances for functions such as position detection, safety interlocking, and light-load action feedback. Its internal sliding clamp-type structure maintains contact stability during frequent operation, reducing malfunctions caused by vibration, making it ideal for smart home modules, small appliance button feedback, and safety limit systems.

In automotive electronics, the G304R series, with its IP68 waterproof and dustproof rating, maintains reliable operation even under prolonged exposure to moisture, mud, and temperature changes. Therefore, it is commonly used in critical components such as door lock position detection, pedal feedback modules, and vehicle light-load signal detection. Its high sealing performance ensures stable conduction even in rain, snow, high humidity, or high-vibration environments.

In automation equipment, the small size of this series of switches, combined with its sliding clamp-type contact structure, makes it ideal for installation in robot end effectors, small automated actuators, and detection devices. The high contact reliability provided by its structure helps improve the overall accuracy and lifespan of the automation system. Overall, the G304R series, with its IP68 rating and durable contact mechanism, provides highly stable solutions for precision control scenarios across multiple industries.
