Schneider Electric ZB4BG410 Key Selector Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BG410 is a 2-position, maintained-action key selector switch operator designed for industrial and commercial control panel applications. The operator uses a black key for position selection, with key removal permitted at any position. The round, metal-bezel head mounts through a standard 22 mm panel cutout. Rated IP69K, NEMA 4X, and NEMA 13, this switch head is built to resist water ingress, shock, and vibration — making it appropriate for washdown environments, outdoor enclosures, and high-vibration machinery. Licensed electricians and panel builders install this component as part of a larger control circuit assembly.

The ZB4BG410 fits standard 22 mm mounting holes and is suited for use in industrial control panels, machine tool enclosures, and process equipment where a maintained two-position key-operated selector is required. The non-illuminated, metal-bezel construction is appropriate for both indoor and outdoor installations where NEMA 4X or NEMA 13 environmental ratings are specified. This operator head pairs with compatible ZB4 series contact blocks and mounting bases per Schneider Electric Harmony XB4 product family conventions described in the manufacturer documentation.

Key Features

• 2-position maintained action — switch holds its selected position without operator input
• Key-operated with black key; key removal allowed at any position for lockout applications
• IP69K ingress protection rating — suitable for high-pressure washdown environments
• NEMA 13 and NEMA 4X rated metal bezel — resistant to oil, dust, and water
• Shock-resistant and vibration-resistant construction for industrial machinery
• Non-illuminated, round head fits standard 22 mm panel cutouts

Compatibility

Designed as an OEM-style operator head for 22 mm industrial control panel assemblies requiring a maintained key selector. Specific contact block and base compatibility should be confirmed against Schneider Electric ZB4 series documentation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize the control panel and follow lockout/tagout procedures before installing or replacing the operator head. The panel cutout must be 22 mm in diameter; verify that the mounting surface thickness is within the range specified in the manufacturer installation sheet. Do not overtighten the mounting nut, as this may crack the bezel or distort the panel cutout.
