It features a black toggle operator in a round, metal-bezel head that mounts through a 22 mm panel hole. The maintained (MA) action means the switch stays in the selected position until physically moved. Rated IP66 and NEMA 4X and 13, it resists water ingress, shock, and vibration, making it suitable for demanding environments where the operator interface is exposed to washdowns or harsh conditions. Licensed electricians and industrial control technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis selector switch head is used in industrial and commercial control panel assemblies where a durable, non-illuminated toggle operator is required. Typical applications include machine control stations, process control panels, and motor control circuits in manufacturing, marine, and infrastructure settings. The metal bezel and IP66-rated construction make it appropriate for both indoor and outdoor enclosures. It is sold as an individual operator head unit, quantity one per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-position maintained action keeps the switch in the selected position without spring return\u003c\/li\u003e\n\u003cli\u003eBlack toggle operator on a round metal-bezel head for clear tactile identification\u003c\/li\u003e\n\u003cli\u003e22 mm panel cutout fits standard 22 mm control station enclosures and panel holes\u003c\/li\u003e\n\u003cli\u003eIP66 and NEMA 4X and 13 rated for water, shock, and vibration resistance\u003c\/li\u003e\n\u003cli\u003eNon-illuminated design for straightforward selector applications without indicator lighting\u003c\/li\u003e\n\u003cli\u003eCertified to UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, and multiple international standards including DNV, GL, and RINA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a 22 mm-class toggle selector switch operator head for use with compatible ZB4 series contact blocks and body assemblies in standard industrial control station configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified electrician or industrial controls technician following applicable NEC and local electrical codes. De-energize and lock out the control panel circuit before installing or replacing any operator head or contact block assembly. Verify that the panel cutout is 22 mm and that the mating contact block is rated for the intended circuit voltage and current before completing the assembly. Do not overtighten the panel-mount nut, as this can crack the bezel or distort the enclosure wall.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperator Type\u003c\/strong\u003e: Toggle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Maintained (MA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperator Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperator Illumination\u003c\/strong\u003e: Non-Illuminated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePanel Hole Diameter\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating\u003c\/strong\u003e: IP66\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 4X, 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResistance Features\u003c\/strong\u003e: Shock-Resistant, Vibration-Resistant, Water-Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.3 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, IEC 60529, IEC 60536, IEC 50102, JIS C 4520, Bureau Veritas, DNV, GL, LROS, RINA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: ZB4BD28\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542012789042,"sku":"ZB4BD28","price":56.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69c87d4ac63ad252dfeab93959380f1e.jpg?v=1785889567","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb4bd28-2-position-selector-switch-22mm","provider":"Voomi Supply","version":"1.0","type":"link"}
