Pushbutton switch Karlik WHE-2, IP54, 250 V AC input, 10 A nominal current

Karlik WHE-2 is a pushbutton switch designed for control circuits and local switching in indoor and protected outdoor environments. The device provides IP54 protection against dust ingress and water splashes, accepts alternating input voltage up to 250 V AC and is rated for a nominal current of 10 A. Its compact form factor and standard mounting dimensions make it suitable for panel installations, machine controls and lighting circuits where a robust, manually operated switching element is required.

Advantages

The switch combines IP54 environmental protection with a straightforward pushbutton operation, offering reliable make/break control for low-voltage AC circuits. With a 10 A nominal current rating and compatibility with up to 250 V AC, the unit supports common control and lighting loads. The construction is intended for use in areas with dust and occasional moisture, providing splash protection while maintaining ease of installation and serviceability.

Suitable for

• Control panels for machinery and equipment
• Local on/off switching of lighting circuits
• Workshops, garages and warehouses with dusty conditions
• Terraces, gazebos and other semi-exposed areas with occasional splashing water

Key specifications

• Protection class: IP54 (protection from dust limited ingress; protection from water splashes)
• Rated input voltage: up to 250 V AC
• Nominal current: 10 A
• Actuation type: pushbutton (momentary or maintained depending on wiring and contact block)
• Typical mounting: panel or control enclosure cut-out
• Application environment: indoor and protected outdoor locations with dust and splash exposure

How to use

Install the pushbutton switch into a compatible panel cut-out and secure it according to the manufacturer's mounting instructions. Wire the switch into the control circuit following applicable electrical standards: connect the supply and load conductors to the appropriate terminals of the contact block, ensure proper grounding of the panel, and verify that the connected load does not exceed 250 V AC and 10 A. After installation, operate the button to confirm correct switching action and secure any terminal covers or protective elements before placing the panel back into service.

Usage recommendations

Use the switch in locations protected from direct water jets and immersion; IP54 provides splash protection but is not suitable for continuous exposure to running water. For installation in environments with high dust accumulation or frequent moisture, inspect and maintain contacts periodically to ensure reliable operation. Verify load characteristics (inrush current, inductive/capacitive nature) and add appropriate protective devices such as fuses or contactors when switching motors or other high-inrush loads.
