## Long description

Karlik 12DWP-3.1 is a single-pole stair switch mechanism designed for two-way (stair) lighting circuits. The unit provides one rocker without a pictogram and is intended as a replacement mechanism to be installed into compatible wall switch frames and faceplates. It is suitable for domestic and commercial corridors, stairways or other locations where switching from two positions is required.
Advantages
The mechanism offers a compact single-rocker design that fits standard compatible switch frames, allowing quick replacement or installation without changing surrounding décor. Its contact configuration supports two-way switching commonly used in stair and corridor lighting installations. The absence of a pictogram gives a neutral look and allows use with a variety of cover plates and rocker caps.
Suitable for
 Two-way (stair) lighting circuits in residential buildings
 Corridor and stairwell lighting in small commercial properties
 Replacement of worn or damaged single-rocker mechanisms in compatible frames
 Installations where a plain rocker without pictogram is preferred
When it may not be suitable
This mechanism is not intended for single-pole switching of heavy industrial loads or as a dimmer control; it is designed for standard lighting circuits within rated limits. It will not fit frames or cover plates that use a different mechanism form factor or mounting system, so compatibility with existing frames must be confirmed before purchase.
Key specifications
 Type: single-rocker stair (two-way) switch mechanism
 Actuation: one rocker (one key), no pictogram
 Intended use: installation into compatible wall switch frames/faceplates
 Application: lighting control for stairways, corridors and similar areas
How to use
Turn off power at the circuit breaker before beginning installation. Remove the existing cover plate and mechanism from the frame, noting wiring connections. Disconnect wires from the old mechanism and attach them to the corresponding terminals of the Karlik mechanism according to the wiring diagram for two-way switching. Secure the mechanism in the frame, reattach the cover plate, and restore power. Test both switch locations to ensure correct two-way operation.
What to consider before purchase
 Confirm mechanical compatibility with your existing switch frame and cover plate dimensions.
 Ensure the mechanism's contact arrangement matches the required two-way wiring on site.
 Verify that the electrical ratings and intended use align with your lighting load and local electrical regulations.
Usage recommendations
Have a qualified electrician perform installation if you are not experienced with household wiring. Use the mechanism only within specified electrical limits and replace any damaged components to maintain safe operation.
