Oven Waterproof and High-Temperature Resistant Miniature Micro Switch

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.

Featuring an ultra-compact design, the overall dimensions are optimized to 12×6×5mm, reducing the size by 30% compared to standard miniature waterproof switches. It can be easily embedded in space-constrained devices such as microwave control panels, miniature sensors, and in-car precision modules, perfectly meeting the needs of compact layouts. It supports three installation methods: vertical, right-angle, and snap-in, without the need to modify the device's mounting position, improving assembly efficiency by 40%.

Relying on Yueqing Tongda's comprehensive quality control system, the FSK-18 undergoes multiple stringent tests from raw materials to finished products:

Raw Material Testing: Spectral analysis of contact materials, elastic fatigue tests of springs, and aging resistance tests of housings to ensure the quality of core components;

Production Testing: Fully automated precision assembly line with key dimensional errors controlled within ±0.02mm to ensure consistent triggering accuracy;

Finished Product Testing: 100% of products pass 8 tests including waterproof soaking, high and low temperature cycling, salt spray corrosion, and durability pressing.

Used for signal control of new energy vehicle charging guns and onboard sensors, with IP67 protection to withstand moisture during rainy day charging, a wide temperature range suitable for extreme in-car temperatures from -25°C to 85°C, certified to the IATF16949 automotive industry standard, and proven fault-free after 18 months of real vehicle testing.
