Industrial control selector

The Schneider Electric ZB4BG7 is a 22 mm keyed selector switch designed for industrial control panels. It provides three distinct positions with a momentary-maintained-momentary action sequence. The metal operator head and chrome-plated bezel suit harsh environments. Operators who need secure, key-limited access to machinery functions will use this device.

Sustained environmental sealing

The switch carries NEMA ratings 1, 2, 3, 4, 4X, 12 and 13 alongside IP66, IP67, IP69 and IP69K protection. These ratings confirm resistance to dust, high-pressure water jets and temporary immersion during continuous operation. The keyed mechanism maintains its tactile action without degradation when exposed to wash-down cycles or outdoor weathering. No cam is included, so contact blocks must be sourced separately for the completed circuit.

Pre-installation checklist

Verify that the panel cut-out matches the 22 mm mounting diameter before ordering. Confirm the key code 455 aligns with your existing key management system. Ensure the intended contact blocks comply with the listed IEC 60947 and UL 508 standards for your application. The switch is restricted from sale in no states, but local electrical codes should still be reviewed.

Questions about this item

Does the 22 mm keyed selector generate any audible noise or heat when left in a maintained position all day?

The switch is a purely mechanical operator with no internal electronics, so it produces no fan noise, coil whine or measurable heat during continuous use.

What separate contact blocks or mounting hardware must I already have for the ZB4BG7 to function?

You need compatible ZB4 or ZB5 contact blocks and a 22 mm panel cut-out; the operator head includes the chrome-plated metal bezel but no cam or contact blocks.

Will the keyed 3-position switch fit the same 22 mm cut-out and NEMA 4X / IP69K rating as my older Schneider push-buttons?

Yes, it uses the standard 22 mm mounting and carries NEMA 1, 2, 3, 4, 4X, 12, 13 plus IP66, IP67, IP69 and IP69K ratings, matching legacy Schneider operators.
