As an upgraded waterproof switch developed by Yueqing Tongda Wire Electric Factory for harsh environments such as high humidity, dust, and outdoor conditions, the FSK-20 series has "IP67 top-level protection and strong load capacity" as its core competitiveness, and is widely suitable for fields with high waterproof performance requirements, such as outdoor lighting, industrial cleaning, automotive electronics, and marine equipment.
Product Introduction
The FSK-20 series adopts an "integrated sealed housing with multilayer waterproof structure" design. The casing is made of weather-resistant PA66-GF30 reinforced nylon, processed through a high-temperature and high-pressure integral molding process to achieve a seamless housing. Key interfaces are equipped with fluororubber seals that are resistant to oil and chemical corrosion, with compression strictly controlled between 0.5-0.7mm. Combined with potting sealing technology and waterproof terminal design, it meets the IP67 protection standard.
Outdoor Large Equipment: Adapted for power control of outdoor high-pole lights, large billboards, and outdoor charging piles, with IP68 protection that can withstand flooding from heavy rain and typhoon conditions. After application by a certain outdoor lighting project company, the equipment's failure rate due to water infiltration dropped from 18% to 0.5%;
Marine Equipment: Custom-designed for circuit control of ship navigation lights and underwater detection instruments. It passed a 24-hour immersion test at 2 meters depth without leakage, and performance showed no deterioration after salt spray testing. A certain marine equipment manufacturer reported that after using the FSK-20, the product's offshore operation failure rate decreased by 75%.
