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

Karlik 4WHE-4 is a compact pushbutton switch with IP54 protection designed for alternating current circuits up to 250 V and a nominal switching current of 10 A. The device is intended for surface and panel installation where resistance to dust and splashes is required. The JUNIOR-series construction offers a sealed enclosure suitable for environments with increased dust and humidity while providing straightforward manual control for start/stop and other general switching functions.

Advantages

The Karlik 4WHE-4 combines a compact footprint with IP54-rated ingress protection, enabling installation in workshops, garages and humid outdoor covered areas where protection against dust and water splashes is needed. Its rated voltage and current (250 V AC, 10 A) make it suitable for a wide range of control circuits, and the standardized pushbutton form factor allows easy replacement or integration into existing control panels. The enclosure design of the JUNIOR series reduces maintenance from dust accumulation and protects electrical contacts from splash exposure.

Suitable for

• Industrial control panels and machinery start/stop buttons
• Surface and panel installations in workshops and garages
• Covered outdoor areas with occasional splashes and high humidity
• General-purpose manual switching in warehouses and service rooms

Key specifications

• Protection rating: IP54 (protection against dust and water splashes)
• Rated voltage: 250 V AC
• Nominal switching current: 10 A
• Actuation type: pushbutton
• Mounting: surface and panel installation compatible

How to use

Install the Karlik 4WHE-4 into a prepared panel cut-out or surface mounting box following local wiring rules and ensuring power is disconnected before wiring. Connect the switch terminals to the control circuit conductors rated for 250 V AC and up to 10 A, and secure the device with the recommended fasteners. After installation, verify correct mechanical operation of the pushbutton and test the electrical switching under load conditions appropriate for the connected equipment.

Usage recommendations

Use the switch in environments consistent with its IP54 rating: rooms exposed to dust, workshops, garages, warehouses, and covered outdoor locations with high humidity or occasional splashes. Do not expose the device to direct water jets or continuous immersion. Periodically inspect and clean surrounding areas to prevent excessive dust accumulation and verify terminal tightness to maintain reliable operation.
