## Long description

The KOS Hydro Line double switch is a robust and reliable electrical component engineered for surface mounting in environments where moisture and dust protection are essential. With its IP44 ingress protection rating, this hermetic switch ensures safe operation in challenging conditions, providing a durable solution for controlling two independent lighting circuits from a single point. Its clean white finish and functional design make it a versatile choice for both residential and utility spaces.
Advantages
The primary benefit of the KOS Hydro Line double switch is its high level of protection against external elements, which significantly extends the lifespan of the device in humid or dusty areas. The surface-mounted design simplifies installation, as it does not require deep wall recesses, making it perfect for retrofitting or mounting on solid surfaces. The dual-circuit control capability allows for efficient management of multiple light sources, while the high-quality materials ensure consistent performance and resistance to mechanical wear over time.
Suitable for
Bathrooms and laundry rooms
Garages and workshops
Basements and storage areas
Covered outdoor patios or porches
This switch may not be suitable for areas exposed to direct, heavy water jets or submersion, as the IP44 rating only covers protection against splashing water. It is also not intended for use in industrial environments with high concentrations of corrosive chemicals or extreme temperatures that exceed the manufacturer's specified operating range.

To install the KOS Hydro Line double switch, ensure the power supply is completely disconnected at the main circuit breaker. Mount the base of the switch securely to the desired surface using appropriate hardware. Connect the electrical wires to the designated terminals according to the wiring diagram, ensuring that the seals are properly seated to maintain the hermetic integrity of the housing. Once connected, attach the cover and test the functionality before restoring power.
What to consider before purchase
Verify that the surface is flat and suitable for surface mounting.
Ensure the IP44 rating meets the specific requirements of your installation environment.
Check that your electrical wiring configuration supports a double switch setup.
For optimal safety and longevity, ensure that all cable entries are properly sealed with the provided gaskets during installation to maintain the IP44 hermetic seal. Avoid using abrasive cleaning agents on the switch surface to prevent damage to the protective finish.
