Stair switch Karlik 7MWP-3 silver metallic — momentary stairway switch, single-pole

Karlik 7MWP-3 silver metallic is a momentary stairway switch designed for reliable control of lighting in staircases, corridors and shared spaces. The device uses a single-pole contact arrangement and operates as an impulse (momentary) switch, making it suitable for timed lighting circuits and multiway stair control systems. Its compact form factor and silver metallic finish integrate into modern interiors and standard wall switch installations.

Advantages

The momentary (impulse) operation enables simple integration with stair timers and central control modules without the need for complex wiring changes. The single-pole design provides straightforward installation in conventional lighting circuits. The metallic finish offers a neutral appearance that matches contemporary decor while the compact dimensions conserve wall space and allow placement in common switch frames.

Suitable for

• Control of staircase and corridor lighting with timed or impulse-operated circuits
• Residential and multi‑unit buildings where momentary switch action is required
• Commercial premises such as office corridors, service stairwells and public access areas
• Integration with stair timers, relays and multiway control systems

Key specifications

• Type of operation: momentary (impulse) switch
• Contact arrangement: single-pole
• Finish: silver metallic
• Mounting: standard flush wall switch mounting compatible with common switch frames
• Application: indoor use for stairway and corridor lighting control

How to use

Install the Karlik momentary stair switch in place of a standard flush-mounted switch following local electrical regulations. Connect the single-pole terminals in line with the lighting circuit or to the control input of a timer or relay module; ensure power is isolated before wiring. Once installed, pressing the switch sends a momentary impulse to the connected timer or relay which then controls the lighting according to the configured timing or multiway control logic.

Usage recommendations

Use with compatible stair timers or control relays designed to accept impulse inputs. Verify that the switch’s electrical ratings match the circuit and load requirements. Have installation and any adjustments performed by a qualified electrician to ensure safe operation and compliance with local codes.
