A 22 mm metal flush push button with blue illumination, momentary action and IP66 protection for industrial control panels
Schneider Electric ZB4BW36 is a 22 mm flush illuminated push button with a blue metal head and metal bezel. It provides momentary action for industrial control panels and machine interfaces. The operator meets NEMA 13 and 4X ratings plus IP66 ingress protection. Compliance includes IEC 60947 standards and UL 508 listing.
This operator fits 22 mm mounting cut-outs in metal enclosures where a momentary illuminated button is required. It is not suitable for applications needing maintained latching action or a different colour indicator. Installations requiring a legend plate or non-metal bezel material should consider other options. The momentary function limits use to push-to-operate circuits only.
The 22 mm cut-out size is the critical dimension that determines whether this operator matches the panel layout. Verify the panel cut-out before ordering to ensure correct installation. All other specifications support this mounting requirement.

The operator requires a compatible 22 mm contact block and light module; both snap onto the metal bezel without tools and must match the control circuit voltage you are using.
Yes, the IP66 and NEMA 4X ratings match the legacy metal range, so the new blue flush head installs in the same 22 mm cut-out and withstands identical high-pressure cleaning cycles.
Press the blue flush head — the contacts should change state only while held, and the integral LED should light steadily when the control voltage is present across the light module terminals.
