Featuring a 22 mm mounting hole diameter and a round, extended mushroom-head operator in black metal, this switch holds its switched state after each press rather than returning to neutral. The metal operator construction and NEMA 4X and 13 ratings make it suitable for environments where moisture, dust, and corrosion resistance are required. Licensed electricians and control panel builders install this type of device in machine control, motor starters, and process equipment enclosures.\u003c\/p\u003e\n\u003cp\u003eThe ZB4BS52 is intended for use in industrial and commercial control panel applications where a maintained contact sequence is required. The 22 mm format is a widely adopted industry standard, making this switch compatible with similarly sized cutouts in existing enclosures and panels. Typical installations include conveyor systems, pump control stations, HVAC equipment panels, and general-purpose machine control circuits where the operator must stay engaged without continuous pressure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaintained (MA) operation — switch holds position after actuation, no spring return\u003c\/li\u003e\n  \u003cli\u003e22 mm mounting hole diameter — standard industrial panel cutout size\u003c\/li\u003e\n  \u003cli\u003eExtended round mushroom-head operator in black metal construction\u003c\/li\u003e\n  \u003cli\u003eNon-illuminated operator — no lamp or LED assembly required\u003c\/li\u003e\n  \u003cli\u003eNEMA 13 and NEMA 4X ratings — resistant to dust, oil, and corrosive washdown environments\u003c\/li\u003e\n  \u003cli\u003eCertified to multiple standards including UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, and others\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install maintained push-button operator for 22 mm industrial control panel assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the control panel before removing or installing any push-button operator. The 22 mm mounting hole should be deburred and clean before seating the operator to ensure the NEMA-rated seal seats correctly. Do not overtighten the mounting nut, as this can damage the operator body or compromise the ingress protection seal.\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\u003eOperator Style\u003c\/strong\u003e: Extended Round Mushroom Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperator Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperator Material\u003c\/strong\u003e: Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIllumination\u003c\/strong\u003e: Non-Illuminated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 4X, 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\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, 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: ZB4BS52\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51540443234610,"sku":"ZB4BS52","price":118.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23075ed67dcb0f24032d7774d01ee611.jpg?v=1785855334","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb4bs52-maintained-push-button-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
