Pushbutton switch Karlik 4WHE-2 250 V AC, 10 A, IP54

Karlik 4WHE-2 is a compact pushbutton switch for AC control circuits up to 250 V with a nominal switching current of 10 A. Built to IP54 ingress protection, the switch offers resistance to dust and splash water, making it suitable for indoor and sheltered outdoor installations. The JUNIOR-series design allows use where dust and moisture are present, including workshops, garages and covered terraces, while providing a manual on/off control point for machinery panels, lighting circuits and other general-purpose switching tasks.

Advantages

The pushbutton delivers stable mechanical operation with a compact footprint that fits standard control panels. IP54-rated protection reduces the risk of dust ingress and protects against water splashes from any direction, and the electrical rating supports common AC loads up to 10 A at 250 V. Its straightforward construction simplifies wiring and replacement in maintenance scenarios, and the robust housing is intended for use in environments with elevated dust or humidity when installed in sheltered locations.

Suitable for

• Control panels for industrial and light-industrial machinery
• Lighting circuits requiring local manual switching
• Workshops, garages and storage areas with dust exposure
• Covered outdoor areas with occasional water splashes (terraces, gazebos)
• General-purpose manual switching in commercial installations

Key specifications

• Rated voltage: AC up to 250 V
• Nominal switching current: 10 A
• Ingress protection: IP54 (protection against dust and water splashes)
• Actuation type: pushbutton
• Design: compact, panel-mount compatible

How to use

Install the pushbutton in a compatible panel cut-out according to the mounting dimensions of the control panel and secure it per the manufacturer's mechanical instructions. Connect the AC supply and load conductors to the switch terminals, ensuring power is isolated before wiring. After wiring, restore power and test the switch operation under the intended load to confirm reliable switching at the rated current and voltage. For sheltered outdoor use, mount the device where it is protected from direct water jets and continuous exposure to rain.

Usage recommendations

Use the Karlik 4WHE-2 where short, manual control pulses or maintained pushbutton action are required; avoid direct exposure to heavy water spray or immersion. For installations in particularly dusty or wet environments, combine the switch with appropriate enclosures or protective covers and follow local electrical regulations and safety practices when performing installation and maintenance.
