## Summary description

Karlik 25MWP-4.1 is a mini single-pole momentary switch mechanism with one rocker and no pictogram in a white matte finish. Designed for installation into compatible wall plates and frames, it serves as a transient (NO/NC depending on wiring) control element for lighting or signaling circuits. Suitable for residential and commercial electrical installations where a compact momentary switch is required.

## Long description

Karlik 25MWP-4.1 is a mini single-pole momentary switch mechanism with one rocker in a white matte finish. Intended for installation into compatible wall plates and frames, this compact module functions as a transient control element in lighting or signalling circuits. Depending on wiring it operates as a normally open or normally closed contact for push-to-make or push-to-break applications. The mechanism is designed to fit standard mounting systems and to be used where a small, unobtrusive momentary switch is required in residential or commercial electrical installations.
Advantages
The compact dimensions and standardized mounting make the Karlik 25MWP-4.1 easy to install into a variety of modular plates and frames. Its single-pole momentary action provides reliable, short-duration switching for bell buttons, door release controls, timed lighting circuits or control inputs to automation systems. The white matte finish reduces visible reflections and integrates discreetly into interiors. The absence of a pictogram allows custom labelling or use where visual icons are not required.
Suitable for
 Momentary control of lights, such as stairwell or corridor lighting with a timer relay
 Doorbell or buzzer push-button
 Door release or intercom control
 Input to home automation or control systems requiring a transient contact
 Replacement or upgrade in modular wall plate installations
When it may not be suitable
This mechanism is a single-pole, momentary device and is not intended for direct switching of high-current loads or permanent on/off switching without an appropriate relay or contactor. It does not include illumination, pictograms, or integrated electronic functions; users needing illuminated switches, multi-way rockers, or additional markings should choose a different model. Also, compatibility depends on using matching frames and plates from the same modular family.
Key specifications
 Type: single-pole momentary switch (one rocker, no pictogram)
 Operation: transient/contact closure — normally open or normally closed depending on wiring
 Finish: white matte
 Mounting: modular wall plate/frame installation
 Use environment: residential and commercial indoor electrical installations
How to use
Install the Karlik 25MWP-4.1 into a compatible modular frame following the manufacturer's wiring diagram and local electrical regulations. Connect the supply and load conductors to the switch terminals according to required function (NO or NC). After mounting and securing the mechanism in the plate, attach the rocker and test the transient action with the circuit de-energised where necessary, then restore power and verify operation. For switching of lighting circuits, pair the mechanism with appropriate relays, timers or automation inputs rather than directly switching high-current fixtures.
What to consider before purchase
 Ensure mechanical and electrical compatibility with your existing wall plates and frame system
 Verify the switch action (momentary) meets the intended use and whether NO or NC wiring is required
 Confirm that the device will not be used to switch loads beyond its intended control purpose; use relays/contactors for high currents
 Check local wiring regulations and, if required, have installation performed by a qualified electrician
Usage recommendations
Use the Karlik 25MWP-4.1 as a control interface for low-voltage signalling, timer-driven lighting, doorbell circuits, or automation inputs. To ensure long-term reliability, avoid direct switching of high-current loads and use appropriate auxiliary devices (relays, timers) when controlling lighting circuits or motors.
