Schneider Electric XB4BG21 Key Switch, 2-Position, 22mm, Black and Steel

The Schneider Electric XB4BG21 is a high-quality, 2-position key-operated selector switch engineered for secure control in industrial environments. Designed for standard 22mm panel mounting, this robust component combines a sleek black and steel finish with industrial-grade durability. It serves as a reliable interface for managing electrical circuits, ensuring that only authorized personnel with the correct key can change the switch state, thereby enhancing safety and operational control in automation systems.

Advantages

This key switch offers superior mechanical reliability and long-term performance in demanding settings. Its construction is resistant to wear and tear, making it an excellent choice for machinery control panels where frequent interaction is required. The key-operated mechanism provides a clear security advantage over standard toggle switches, preventing unauthorized access or accidental operation. Furthermore, the 22mm mounting diameter ensures compatibility with a wide range of standard industrial enclosures and control stations.

Suitable for

• Industrial machinery control panels
• Automation and process control systems
• Secure access points for electrical equipment
• Control stations requiring restricted operation

When it may not be suitable

This switch is not intended for applications requiring rapid, frequent switching by multiple users without a key. It is also not suitable for environments where the key could be lost or where immediate, emergency-style access is required without the use of a physical key.

Key specifications

• Mounting diameter: 22mm
• Material: Black and steel construction
• Mounting type: Plate mounted
• Quantity: 1 piece per pack

How to use

To install the Schneider Electric XB4BG21, insert the unit into a pre-drilled 22mm hole on your control panel and secure it using the provided mounting hardware. Once installed, the switch is operated by inserting the key and rotating it to the desired position. The key can be used to lock the switch in place, ensuring the circuit remains in the selected state until authorized personnel return to change it.

What to consider before purchase

• Ensure your control panel has a standard 22mm mounting hole.
• Verify that the 2-position functionality meets your circuit requirements.
• Consider the physical space behind the panel to accommodate the switch body.
• Confirm that the key-operated security level is appropriate for your specific application.

Usage recommendations: Regularly inspect the key mechanism for debris and ensure the mounting nut remains tight to maintain the integrity of the panel seal. Keep spare keys in a secure, accessible location to prevent operational downtime.
