Automatic Gear Shifter Detection Switch with Positioning Pin

The core competitiveness of the FSK-18 lies in its "perfect balance of miniaturization and waterproofing," using a patented sealing structure design: high-elasticity nitrile rubber sealing rings are embedded at the shell joints, combined with an overall potting process to fill internal gaps, completely blocking the intrusion paths of water vapor and dust. The protection level reaches IP67, capable of withstanding 30 minutes of immersion at a depth of 1 meter, ensuring stable operation in environments such as bathrooms, outdoor rain, and humid industrial workshops.

The shell is made of flame-retardant PA66 reinforced nylon, treated with high-temperature modification, providing both flame resistance (UL94 V-0) and anti-aging performance. The operating temperature range covers -25℃ to 85℃, capable of withstanding high and low temperature cycling impacts, preventing material cracking or performance degradation in extreme environments. The contact system uses highly wear-resistant silver alloy material, optimized with a vacuum plating process. The initial contact resistance is ≤50mΩ, insulation resistance is ≥100MΩ (500VDC), and the terminal withstand voltage reaches 1500V AC, effectively preventing leakage and contact oxidation in humid environments.

Equipped with a miniature fast-action trigger mechanism, the trigger travel can be customized between 0.4-1.5mm, with an operating force range of 1-3.5N. It can achieve precise triggering without a lever and can also be configured with various actuators such as needle plungers or roller levers according to different scenarios, meeting requirements for different installation angles and triggering methods. The optimized spring structure ensures instantaneous contact switching, effectively reducing arcing, with a mechanical lifespan exceeding 100,000 cycles and an electrical lifespan of 10,000 cycles, making it suitable for high-frequency operation environments.
