## Long description

The KOS Hydro Line intermediate switch is a robust electrical component engineered for reliable performance in environments where moisture and dust protection are essential.

The surface-mounted design simplifies installation on walls where recessed boxes are not available or desired. Built with high-quality materials, the unit offers excellent resistance to environmental stressors, ensuring that the switching mechanism remains responsive and secure over extended periods of use. Its neutral white finish allows it to blend discreetly with most architectural styles and wall surfaces.

When it may not be suitable
