Pushbutton switch Karlik WHE-1, IP54, 250 V AC input, 10 A nominal current

Karlik WHE-1 is a pushbutton switch designed for control applications in wall-mounted control panels, machinery controls and general-purpose installations. The device provides IP54 protection against dust ingress and splashing water, accepts AC input voltage up to 250 V and is rated for a nominal switching current of 10 A. It belongs to the JUNIOR series, suitable for environments with dust and elevated humidity where splash protection is required but full immersion is not allowed.

Advantages

The Karlik WHE-1 combines a compact pushbutton form factor with IP54-rated protection, allowing installation in workshops, garages, warehouses and outdoor covered areas such as terraces and gazebos. Its 250 V AC compatibility and 10 A nominal current rating make it suitable for many control circuits, while the JUNIOR series design emphasizes reliable operation in dusty and humid conditions without exposure to direct water jets or immersion.

Suitable for

• Wall-mounted control panels in industrial and commercial buildings
• Machine start/stop and control circuits
• Workshops, garages and warehouses with dust presence
• Covered outdoor areas with occasional splashing (terraces, gazebos)
• General-purpose switching where IP54 splash protection is sufficient

Key specifications

• Protection class: IP54 (protection against dust and splashing water)
• Rated input voltage: up to 250 V AC
• Nominal switching current: 10 A
• Actuation type: pushbutton
• Series: JUNIOR (designed for dusty and humid environments)

How to use

Install the Karlik WHE-1 pushbutton in accordance with local electrical regulations and the panel manufacturer’s mounting recommendations. Connect the incoming and outgoing conductors to the switch terminals rated for 250 V AC and 10 A, ensuring correct tightening of terminal screws and appropriate wire cross-section for the current. The device is intended for control and signalling circuits and must not be exposed to direct water jets or submerged. Verify correct mechanical and electrical operation after installation and before regular use.

Usage recommendations

Use the switch indoors or in covered outdoor locations where splashing is possible but immersion is not. For environments with continuous high-pressure water exposure or full immersion, select a higher IP-rated device. Periodically inspect the switch and surrounding enclosure for accumulated dust or moisture and perform maintenance as required to preserve reliable operation at the specified 250 V AC / 10 A ratings.
