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

Karlik WHE-4 is a pushbutton switch designed for control and switching of AC circuits up to 250 V. With an IP54 protection rating and a nominal current of 10 A, this switch is intended for indoor and protected outdoor installations where resistance to dust and splashing water is required. The JUNIOR series construction provides durability in environments with dust and moisture, making it suitable for control panels, machinery start/stop circuits and lighting circuits that do not require full immersion protection.

Advantages

The device combines a compact pushbutton design with IP54 ingress protection, offering reliable operation in dusty and damp locations. A 10 A nominal current rating allows safe switching of typical control and lighting loads up to 250 V AC. The modular form factor and standard mounting dimensions simplify replacement and integration into existing control panels or switch assemblies. Materials and sealing provide splash resistance from any direction, while the rated voltage ensures compatibility with common AC mains circuits.

Suitable for

• Control panels and operator stations
• Start/stop controls for industrial and light machinery
• Lighting circuits in garages, workshops and utility rooms
• Terraces, gazebos and other covered semi-outdoor areas

How to use

Install the Karlik WHE-4 pushbutton in accordance with local electrical codes and the panel manufacturer’s instructions. Ensure power is disconnected before wiring. Mount the unit in a compatible cutout or panel aperture and connect supply and load conductors to the switch terminals using appropriately rated cable and terminals. Verify secure mechanical fastening and that sealing surfaces are intact to retain IP54 protection. Restore power and test switching operation under normal load conditions.

Usage recommendations

Use the switch in locations protected from direct water jets and prolonged immersion. For reliable lifetime and maintained IP54 performance, avoid exposure to excessive dust build-up and perform periodic inspection of seals and terminal connections. Select wiring and protective devices that match the 250 V AC / 10 A ratings and follow industry safety practices during installation and maintenance.
