It features a black toggle operator with a round head and non-illuminated bezel, housed in a plastic head rated for IP66 ingress protection and NEMA 4X and 13 environments. This operator is shock-resistant, vibration-resistant, and water-resistant, making it suitable for demanding installation conditions. It is installed by licensed electricians and control panel builders working on machine control, process equipment, and automation systems. The ZB5AD28 is a switch operator only and requires a compatible contact block to complete the assembly.\u003c\/p\u003e\u003cp\u003eThis operator suits industrial control stations, enclosures, and machine panels requiring a maintained 2-position switching function. It fits a 22 mm round mounting hole, a standard diameter across industrial control devices. Typical applications include motor start-stop controls, selector functions for multi-speed or directional motor circuits, and mode selection on automated process equipment. The maintained operation type means the toggle holds its selected position until manually moved, making it appropriate for persistent on-off or dual-mode circuit control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-position maintained operation holds selected state without spring return\u003c\/li\u003e\n\u003cli\u003eBlack toggle operator with round head for standard control panel aesthetics\u003c\/li\u003e\n\u003cli\u003e22 mm round mounting hole diameter for compatibility with standard industrial cutouts\u003c\/li\u003e\n\u003cli\u003eIP66 and NEMA 4X and 13 ratings provide resistance to dust, water jets, and oil splashing\u003c\/li\u003e\n\u003cli\u003eShock-resistant and vibration-resistant construction for industrial environments\u003c\/li\u003e\n\u003cli\u003eNon-illuminated operator keeps installation wiring simple with no pilot light circuit required\u003c\/li\u003e\n\u003cli\u003eCertified to UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, and multiple international standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style selector switch operator for use in 22 mm industrial control station assemblies.

Disconnect and lock out all power to the control enclosure before removing or installing switch operators or contact blocks. The 22 mm mounting hole should be deburred and verified to dimension before insertion. Do not over-torque the mounting nut, as the bezel material is plastic and may crack under excessive force.\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: Toggle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperator Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperator Illumination\u003c\/strong\u003e: Non-Illuminated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel Material\u003c\/strong\u003e: Plastic\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\u003eStandards\u003c\/strong\u003e: UL 508, UL Listed, CSA, CSA C22.2 No. 14, EN\/IEC 60947-1, EN\/IEC 60947-5-1, EN\/IEC 60947-5-4, IEC 60529, IEC 60536, JIS C 4520, Bureau Veritas, DNV, GL, LROS, RINA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: ZB5AD28\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541314601266,"sku":"ZB5AD28","price":51.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7f651572fbe4a13f904e68832207177.jpg?v=1785872155","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb5ad28-2-position-selector-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
