It features a flush-style, round red metal pushbutton head with a maintained (MA) operation type, meaning the switch holds its actuated position until pressed again. The metal construction and NEMA 4X and 13 ratings make it suitable for environments where moisture, dust, and corrosion resistance are required. Licensed electricians and industrial control technicians install this switch as part of operator interface stations, machine control panels, and automated equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThis push-button switch fits standard 22 mm mounting hole cutouts, which is the most common panel-mount format in industrial control applications. It is appropriate for both new panel builds and replacement installations in existing equipment. The red actuator color conventionally signals stop, off, or emergency-related functions in control circuit wiring. This switch is suited for use in manufacturing, process control, marine, and other demanding commercial or industrial environments where certified components are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaintained (MA) operation holds switch position after actuation without continuous operator force\u003c\/li\u003e\n  \u003cli\u003eFlush-mount round red metal pushbutton head for standard operator interface panels\u003c\/li\u003e\n  \u003cli\u003e22 mm mounting hole diameter fits the most common industrial panel-mount cutout format\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X and 13 ratings provide resistance to dust, water, and corrosive environments\u003c\/li\u003e\n  \u003cli\u003eCertified to UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, and multiple marine standards including DNV, GL, and RINA\u003c\/li\u003e\n  \u003cli\u003eMetal pushbutton construction for durability in heavy-use industrial settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install push-button switch for industrial control panels and operator interface stations using standard 22 mm panel-mount cutouts.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC guidelines and applicable local codes. De-energize the control panel and verify the absence of voltage before mounting or wiring this switch. The 22 mm mounting hole should be clean and free of burrs before inserting the switch body. Follow the manufacturer wiring diagram for contact block termination and verify correct operation in both actuated and released states before returning the panel to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Push-Button\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Maintained (MA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush Button Style\u003c\/strong\u003e: Flush\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush Button Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush Button Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePush Button Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 4X, 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 1.5 inches x 1.5 inches x 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL Listed, UL 508, CSA, CSA C22.2 No. 14, EN\/IEC 60947-1, EN\/IEC 60947-5-1, EN\/IEC 60947-5-4, EN\/IEC 60947-5-5, Bureau Veritas, DNV, GL, JIS C 4520, LROS, RINA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCHNEIDER ELECTRIC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZB4BH04\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51538965168434,"sku":"ZB4BH04","price":28.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e6b704b418de9b49794891c3dd2477e.jpg?v=1785831173","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb4bh04-push-button-switch-22mm-maintained","provider":"Voomi Supply","version":"1.0","type":"link"}
