The operator features a red, round, extended (straight) metal button with a 22 mm mounting hole diameter and an integrated LED lamp. Maintained-action (MA) operation means the switch holds its position on actuation and returns only when actuated again, making it suitable for latching control functions. The metal construction and NEMA 4X and 13 ratings provide resistance to dust, water, and corrosive environments. Licensed trades and panel builders install this switch in machine control, process automation, and electrical enclosure applications.\u003c\/p\u003e\n\u003cp\u003eThis switch is suited for use in both commercial and industrial control systems where a durable, illuminated operator is required. The 22 mm mounting diameter is a widely adopted industry standard, and the extended round button profile provides clear tactile and visual feedback for operators. Typical installation scenarios include motor starter panels, conveyor control stations, pump control enclosures, and general-purpose industrial machinery. The LED illumination supports status indication at the operator level. NEMA 4X and 13 ratings make this switch appropriate for washdown, outdoor, or moderately corrosive environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaintained (MA) operation holds switch state after actuation\u003c\/li\u003e\n  \u003cli\u003eIlluminated with integrated LED lamp for visual status indication\u003c\/li\u003e\n  \u003cli\u003eRed, round, extended (straight) button profile for clear operator identification\u003c\/li\u003e\n  \u003cli\u003eMetal push-button construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003e22 mm mounting hole diameter compatible with standard industrial panel cutouts\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X and 13 rated for dust-tight, watertight, and corrosion-resistant installations\u003c\/li\u003e\n  \u003cli\u003eCertified to UL 508, CSA C22.2 No. 14, EN\/IEC 60947-5-1, and multiple additional international standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation operator for 22 mm industrial push-button control stations accepting maintained-action, illuminated, extended round metal operators.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the NEC and applicable local codes.
