Schneider Electric ZB4BZ2105 Pushbutton Switch Guard

Product Description

The SCHNEIDER ELECTRIC ZB4BZ2105 is a yellow, round, extended mushroom head pushbutton switch guard designed to protect 22mm pushbutton operators from accidental actuation. Made from plastic, this nonilluminated guard fits over standard 22mm pushbutton assemblies and provides a physical barrier that reduces the risk of unintended activation in industrial and commercial control panel applications. Electricians and control panel technicians install this type of guard as part of machine safety and operator interface builds. The guard is sold individually and installs without special tools.

This switch guard is suited for use with 22mm pushbutton stations in industrial control panels, manufacturing equipment, HVAC equipment control enclosures, and similar operator interface assemblies. It is intended for XB4 series 22mm pushbutton operators. The yellow color is commonly used to signal caution or to visually distinguish specific control functions on a panel. The extended mushroom head profile makes the guard appropriate for applications where a larger actuation area is present and additional protection from accidental contact is needed.

Key Features

• Yellow color for visual identification and caution designation on control panels
• Extended mushroom head profile guards against accidental pushbutton actuation
• Round button shape compatible with standard 22mm round pushbutton operators
• Nonilluminated design for use where indicator lighting is not required
• Plastic construction keeps the assembly lightweight
• Sold as a single unit for precise replacement or new-build quantities

Compatibility

Designed for use with 22mm pushbuttons in the XB4 series. Confirm operator head profile and panel cutout dimensions before installation to ensure proper fit.

Installation Notes

Installation is typically performed by a licensed electrician or qualified control panel technician. De-energize the control panel and follow lockout/tagout procedures before servicing any pushbutton operator or guard. Verify that the guard seats fully and does not interfere with the travel or reset of the pushbutton operator. Work should conform to applicable NEC requirements for industrial control panels.
