2-position switch Ø22 with key stable 4 multi-chips round metallic ZB4BG4K

Key switch for control panels – reliability and safety

This round, metal key switch is a robust solution for applications requiring an additional level of security. Designed for mounting in 22.5 mm diameter holes, it is ideal for control cabinets, machines and industrial equipment. The construction with a metal front ring ensures durability and resistance to mechanical damage, and the high degree of protection IP66 guarantees tightness against dust and water.

Functionality and application

The switch offers two switching positions, allowing control of two circuits or functions. The key mechanism prevents accidental switching on or off of the device, which is particularly important in critical applications. Non-latching operation means the switch remains in the selected position until the setting is changed with the key. This gives the user full control over the circuit status.

The switch finds application in:

• Control cabinets
• Machines and industrial equipment
• Applications requiring protection against unauthorized access
• Operator panels
• Automation devices

Construction and characteristic features

Made of high-quality materials, the switch is characterized by a solid construction and long service life. The black control element and chrome front ring provide an aesthetic appearance. The key locking mechanism provides additional security, and the round lens shape makes it easy to integrate with the control panel. The lack of backlight does not limit the functionality of the device in typical industrial applications. The non-latching design ensures stable switch position retention, which is important in applications requiring precise control. The IP66 protection class guarantees resistance to harsh environmental conditions, such as dust and moisture.
