## Long description

The Karlik DECO 25DWP-3.1 is a high-quality single-key staircase switch mechanism designed for efficient lighting control in residential and commercial environments. Finished in a sophisticated matte white, this switch integrates seamlessly into modern interior designs while providing reliable performance. It is specifically engineered to allow for the control of a single light source from two distinct locations, making it an essential component for hallways, staircases, and large rooms where multi-point switching is required.
Advantages
This staircase switch mechanism stands out due to its robust construction and compatibility with the extensive Karlik DECO series range. The matte white finish offers a clean, contemporary look that resists fingerprints and blends well with various wall colors. Its design ensures smooth, tactile operation, providing consistent feedback with every press.

Suitable for
Controlling hallway lighting from two ends

Residential and commercial electrical installations
When it may not be suitable
This switch is designed specifically for staircase (two-way) switching applications and may not be suitable for standard single-point on-off control without proper wiring adjustments. It is not intended for outdoor use or in environments with high moisture levels unless installed within an appropriate IP-rated enclosure.
Key specifications
Type: Single-key staircase switch mechanism
Color: Matte white
Series: Karlik DECO
Function: Two-way lighting control

How to use
The switch mechanism is designed for installation into a standard wall box. It requires a three-wire configuration to function as a staircase switch, allowing two switches to control the same light. Once installed, the switch is operated by pressing the single key to toggle the light state. It is compatible with standard DECO series frames, which should be snapped into place after the mechanism is secured to the wall.
What to consider before purchase
Ensure your electrical wiring supports two-way switching
Verify compatibility with your existing DECO series frames
Consult a qualified electrician for installation
Check if the matte white finish matches your current interior decor
Usage recommendations
For optimal safety and performance, always ensure the power supply is disconnected at the main circuit breaker before beginning any installation work. If you are not experienced with electrical wiring, it is highly recommended to hire a certified professional to perform the installation.
