It features a black, non-illuminated handle with a round head and a metal bezel that mounts through a 22mm panel hole. The momentary (MO) operation means the switch returns to center when released, making it well-suited for jog, inch, or temporary-command functions. The IP69K ingress protection rating and shock- and vibration-resistant construction support use in demanding environments. Licensed electricians and control panel builders are the primary installers of this switch operator.\u003c\/p\u003e\u003cp\u003eThis selector switch operator is used in industrial and commercial control panels where a 22mm mounting footprint is standard. Its NEMA 13 and 4X ratings make it appropriate for locations exposed to oil, dust, and washdown conditions. The momentary 3-position configuration supports applications such as forward-stop-reverse, jog-left and jog-right, or other temporary-command circuits common in machine control and process automation. It is sold as a standalone operator head and requires a compatible contact block for circuit completion.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-position momentary operation returns to center on release\u003c\/li\u003e\n\u003cli\u003e22mm panel cutout diameter fits standard 22mm control station hardware\u003c\/li\u003e\n\u003cli\u003eIP69K rated for high-pressure washdown and dust-tight environments\u003c\/li\u003e\n\u003cli\u003eNEMA 13 and NEMA 4X rated for oil-tight and corrosion-resistant applications\u003c\/li\u003e\n\u003cli\u003eMetal bezel construction with shock- and vibration-resistant design\u003c\/li\u003e\n\u003cli\u003eNon-illuminated black handle for clear operator identification\u003c\/li\u003e\n\u003cli\u003eMeets UL 508, CSA, and multiple IEC standards including EN\/IEC 60947-5-1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style 22mm selector switch operator compatible with standard 22mm control station contact block assemblies in industrial panel applications.

De-energize the control panel and lock out\/tag out all power sources before removing or installing switch operators. The operator head mounts through a 22mm panel cutout and requires a separately sourced contact block to complete the switching circuit. Do not exceed the contact block ratings when applying this operator in a circuit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Momentary (MO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Diameter\u003c\/strong\u003e: 22mm\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\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\u003eDimensions\u003c\/strong\u003e: 1.3 inches x 1.3 inches x 1.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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, EN\/IEC 60947-5-5, IEC 60529, IEC 60536, IEC 50102, JIS C 4520, Bureau Veritas, DNV, GL, LROS, RINA\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: ZB4BJ8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51541049540914,"sku":"ZB4BJ8","price":35.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/036a98dc2e528485b98a7be25f877230.jpg?v=1785867840","url":"https:\/\/voomisupply.com\/products\/schneider-electric-zb4bj8-3-position-momentary-selector-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
