Schneider Electric ZB4BG612 Key Selector Switch 22mm

Product Description

The SCHNEIDER ELECTRIC ZB4BG612 is a 2-position momentary key-operated selector switch designed for industrial control panel applications. It features a round, non-illuminated black key operator with a metal bezel and a 22 mm panel cutout diameter. The momentary (MO) action returns the switch to the neutral position when the key is released, with key removal allowed in the left position only. Rated IP69K for high-pressure washdown environments and listed to NEMA 13 and 4X enclosure standards, this switch is built for demanding service conditions. Licensed electricians and panel builders install this component in machine control, process equipment, and industrial automation assemblies.

The ZB4BG612 is suited for use in both indoor and outdoor industrial environments where moisture, dust, and vibration resistance are required. The shock-resistant and vibration-resistant construction makes it appropriate for mobile equipment, food processing facilities, marine applications, and heavy industrial machinery. Its IP69K ingress protection rating means it withstands high-temperature, high-pressure water jets, making it a reliable choice for washdown-duty control panels in processing plants and similar settings.
