Pushbutton switch Karlik 4WHE-6, IP54, 250 V AC input, 10 A nominal current

Karlik 4WHE-6 is a pushbutton switch with IP54 protection designed for switching and control of alternating current circuits up to 250 V AC. Rated for a nominal current of 10 A, the device suits compact control panels, machinery interfaces and general-purpose on/off applications where basic dust and splash resistance is required. The JUNIOR-series design allows installation in environments with dust and elevated humidity while providing protection against splashing water from any direction.

Advantages

The pushbutton offers a compact mechanical design and straightforward electrical connections that simplify integration into control systems. IP54 protection reduces the risk of dust ingress and provides splash resistance, extending service life in non-submerged, dusty or humid locations. A 10 A nominal current rating and 250 V AC voltage compatibility make the switch suitable for a wide range of low- and medium-power circuits, and the standardized mounting dimensions enable replacement or upgrade in existing panels.

Suitable for

• Control panels in industrial and residential installations
• Machine control interfaces and start/stop circuits
• Workshops, garages and storage areas with dust presence
• Terraces, gazebos and other locations with elevated humidity (non-submerged)
• General-purpose on/off switching of lighting and small motors within rated limits

Key specifications

• Ingress protection: IP54 (protection against dust ingress sufficient for operation and protection against splashing water)
• Rated voltage: 250 V AC
• Nominal current: 10 A
• Actuation type: pushbutton
• Intended mounting: panel / control board installation

How to use

Install the Karlik 4WHE-6 pushbutton into a compatible panel cutout and secure it according to the manufacturer’s mechanical instructions. Connect the live and neutral conductors to the switch terminals in accordance with the circuit diagram and applicable electrical regulations, ensuring power is disconnected before wiring. After installation, verify correct operation by actuating the button and checking circuit continuity or the downstream load function. Avoid immersion in water and prevent direct long-term exposure to heavy sprays.

Usage recommendations

Use the switch within its rated limits (250 V AC, 10 A) and in locations consistent with IP54 rating: suitable for dusty rooms and areas with splashes or high humidity but not for direct water jets or submersion. Periodically inspect terminals for secure connections and signs of corrosion in humid environments and replace the device if mechanical wear or ingress-compromising damage is detected.
