## Long description

The Ospel ŁNH-3NS/00 is a robust hermetic staircase switch engineered for reliable lighting control in challenging environments. This surface-mounted switch is designed to withstand exposure to dust and moisture, making it a dependable choice for utility areas. With a clean white finish and a durable construction, it integrates seamlessly into various industrial or residential settings while providing consistent electrical performance at 16A and 250V.
Advantages
The primary benefit of this switch is its IP44 ingress protection rating, which ensures that the internal components are shielded against splashing water and solid objects. The use of high-quality screw terminals facilitates a secure and stable electrical connection, reducing the risk of loose wiring over time. Its design is specifically optimized for staircase lighting configurations, allowing for the convenient control of a single light source from two different locations. The compact dimensions allow for installation in tight spaces without compromising ease of operation.
Suitable for
Garages and workshops
Basements and utility rooms
Covered outdoor areas such as porches or patios
Staircases requiring multi-point lighting control
When it may not be suitable
This switch is not intended for direct exposure to heavy rain or water jets, as the IP44 rating only provides protection against splashing. It is also not suitable for flush-mounted installations, as it is specifically designed for surface mounting.

How to use
Installation should be performed by a qualified professional to ensure safety and compliance with local electrical codes. The switch is designed for surface mounting, meaning it should be attached directly to the wall surface using appropriate hardware. Once mounted, the wires are connected to the internal screw terminals according to the wiring diagram for staircase switching. Ensure the power supply is disconnected before beginning any installation work to prevent electrical shock.
What to consider before purchase
Verify that the surface mounting style is compatible with your wall structure.
Ensure the IP44 rating meets the environmental requirements of your installation site.
Confirm that your existing wiring supports a staircase switching configuration.
Usage recommendations
For optimal longevity, ensure that the cable entries are properly sealed during installation to maintain the integrity of the IP44 protection. Periodically check the screw terminals for tightness if the switch is installed in an area subject to vibrations.
