Product Description
The G11 Series DPDT Waterproof Limit Micro Switch is a high-performance micro limit switch designed for complex industrial and automotive electronic environments. It utilizes a double-break switching mechanism (DPDT) to achieve simultaneous switching of two circuits, ensuring stable and reliable signal output. Its compact size and structure make this waterproof limit micro switch easily integrated into space-constrained mechanical systems, providing precise travel detection and control for precision equipment. Rated at 5A 250VAC, it is suitable for a variety of low- and medium-power circuit control applications.
In industrial automation, this DPDT micro switch is widely used in robotic arms, conveyors, lifting devices, and production line automation control systems. When a moving part reaches a set limit, the internal double-pole double-throw (DPDT) contacts instantly switch via a snap-action mechanism, enabling the device to stop, reverse, or safely shut down. With an operating temperature range of -25°C to +85°C and a maximum humidity of 85% RH, it maintains excellent triggering accuracy and stable performance even in high-temperature, high-humidity, and vibrating environments. Furthermore, its durable design, with an electrical life of over 50,000 cycles and a mechanical life of 2,000,000 cycles, ensures long-term reliability in high-frequency operation.
In automotive electronic systems, the G11 Series DPDT Waterproof Limit Micro Switch is commonly used in functional modules such as power tailgate control, brake system monitoring, and vehicle displacement and travel feedback. Its highly sensitive trigger mechanism ensures accurate signal transmission, prevents false operation, and improves the responsiveness of the vehicle's electronic controls. Importantly, this product is the IP67 limit switch, demonstrating its meticulous design by a micro switch manufacturer. Its fully sealed construction effectively prevents dust and liquid intrusion, ensuring stable operation even in extreme environments such as humidity, mud, rain, and snow. This feature enables this switch to play a critical role in safety and control in both automotive and industrial automation equipment, providing a solid foundation for long-term system reliability.

Application
In industrial automation equipment, this limit switch is commonly used for limit detection in robotic arms, conveyors, and processing equipment. When a moving part reaches a set position, the switch's internal spring mechanism triggers the contacts with a tiny stroke, rapidly switching the circuit and enabling precise stopping or reversing of the device. Its electrical life: over 50,000 cycles and mechanical life: 2,000,000 cycles ensure long-term, high-frequency operation and reliability, providing safety assurance for industrial production.
In the automotive electronics field, the G11 Series DPDT Waterproof Limit Micro Switch is primarily used in power tailgates, braking systems, and body control modules to detect mechanical position or travel end points. Its IP67 rating provides excellent water and dust resistance, effectively preventing dust intrusion and performance loss caused by temporary submersion in water. This design ensures the switch maintains high sensitivity and stability even in harsh climates or outdoor environments, providing reliable signal input and feedback for automotive electronic control systems.
