Water Heater with IP67 Waterproof Switch

The FSK-18 Series adopts a dual-protection structure of "integrated sealed housing + nitrile rubber seal ring": the housing is made of high-rigidity PA66 material, precision-molded with no seams at the joints; the seal ring is embedded in the housing groove, with a compression amount controlled between 0.3-0.5mm, achieving complete dust isolation (IP6X) and no leakage after 30 minutes of immersion in 1-meter water depth (IPX7). Test data shows that in scenarios such as kitchen oil spray, outdoor heavy rain washing, and industrial cleaning solution immersion, the moisture rate of internal components is 0, completely solving the problems of "water-induced short circuit and dust-induced jamming" of traditional switches.

The characteristics of the waterproof switch mainly include the following aspects:

Waterproof performance: The waterproof switch has a waterproof design and can withstand the intrusion of water and moisture. They usually use special sealing structure and waterproof material to ensure reliable operation in wet environment. The core competitiveness of the FSK-18 series waterproof switches lies in their excellent protective performance and stable electrical characteristics. All products in the series have obtained IP67 protection certification. The housing features an integrated sealed structure, with joint areas fitted with aging-resistant nitrile rubber sealing rings, fully preventing dust ingress and enduring immersion in water up to 1 meter deep for 30 minutes. Even in environments such as kitchens with oil splashes, outdoor rainy conditions, or industrial cleaning sprays, the internal components remain protected against moisture and short circuits.

The electrical performance is equally reliable: the contacts are made of high-purity silver-palladium alloy and undergo vacuum coating treatment, with an initial contact resistance of ≤5 mΩ. They can stably carry 10A-20A AC current (rated voltage 250V AC), meeting the power requirements of most medium-power devices. The triggering mechanism uses reinforced springs and rocker components, providing a mechanical lifespan of up to 100,000 press cycles and an electrical lifespan exceeding 80,000 cycles. This ensures more than 5 years of stable operation for high-frequency usage appliances such as kitchen equipment and outdoor lighting.
