The operator uses a black key that can be removed only in the left position, preventing unauthorized or accidental actuation. The unit features a round, non-illuminated metal bezel head with a 22 mm mounting hole diameter. Rated IP69K, it withstands high-pressure washdowns, shock, vibration, and water ingress — making it well suited for demanding industrial and food-processing environments. The switch weighs 0.15 pounds and carries NEMA 4X and NEMA 13 ratings alongside a broad set of international certifications.\u003c\/p\u003e\u003cp\u003eThis key selector switch is appropriate for use in industrial machinery, automated equipment, and control stations where a lockout or access-restricted operator interface is required. Its maintained-action operation means the switch stays in the selected position after the key is turned, making it suitable for mode selection, enable\/disable functions, and safety interlock circuits in both light and heavy industrial settings. Electricians and control panel builders typically install this component during new panel builds or maintenance replacements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-position maintained (MA) operation — holds selected position without continuous operator input\u003c\/li\u003e\n\u003cli\u003eBlack key operator with left-position key removal for access restriction\u003c\/li\u003e\n\u003cli\u003eIP69K ingress protection — rated for high-pressure, high-temperature washdown environments\u003c\/li\u003e\n\u003cli\u003eNEMA 13 and NEMA 4X enclosure ratings for oil and water resistance\u003c\/li\u003e\n\u003cli\u003eRound metal bezel head — shock-resistant, vibration-resistant, and water-resistant construction\u003c\/li\u003e\n\u003cli\u003e22 mm mounting hole diameter — fits standard 22 mm panel cutouts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style operator head for use with 22 mm Harmony XB4 series contact block and body assemblies in standard industrial control panel applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC and applicable local codes. De-energize the control panel and verify zero energy state before removing or installing any operator components. A 22 mm panel knockout or drilled hole is required for proper mounting. Do not overtighten the bezel nut, as this can crack the panel or distort the mounting threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Maintained (MA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperator Type\u003c\/strong\u003e: Key\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKey Removal Position\u003c\/strong\u003e: Left\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\u003eHead Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 13, 4X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating\u003c\/strong\u003e: IP69K\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: 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: Bureau Veritas, CSA, CSA C22.2 No. 14, DNV, EN\/IEC 60947-1, EN\/IEC 60947-5-1, EN\/IEC 60947-5-4, EN\/IEC 60947-5-5, GB 14048.5, GL, IEC 50102, IEC 60529, IEC 60536, LROS, RINA, UL 508, UL Listed\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: ZB4BG220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542545203506,"sku":"ZB4BG220","price":121.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/20469c8fbbf8daa0f9da88dce2d601ce_1ce666f6-13bb-4755-bb47-096a2e38c389.jpg?v=1785903344","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb4bg220-key-selector-switch-22mm","provider":"Voomi Supply","version":"1.0","type":"link"}
