Product Description

WEIPENG® is a leading China manufacturers, suppliers and exporter of Integrated Charging Gun Compact Waterproof Micro Switch

Product Introduction 


For the high power demands of industrial equipment and large outdoor electrical appliances, the FSK-20 has been specifically upgraded in terms of electrical performance: the contacts are made of 99.9% high-purity silver-palladium alloy, with surface hardness enhanced through vacuum sputtering technology, an initial contact resistance of ≤5mΩ, a rated load of up to 20A (250V AC), and a peak load supporting 30A instantaneous switching. It can reliably accommodate circuit control for medium-to-high power equipment such as industrial washers, outdoor charging stations, and large aquarium devices, preventing contact erosion and performance degradation due to current overload. The actuator structure features a "reinforced spring with dual contact linkage" design, achieving a mechanical life of over 120,000 press cycles and an electrical life of more than 80,000 cycles. In industrial scenarios with high-frequency daily switching, it can provide stable operation for over 6 years.
