It features a round, extended straight-profile blue metal button with no illumination. The operator is rated for NEMA 4X and NEMA 13 environments, making it suitable for wet, dusty, and corrosion-exposed locations. Licensed electricians and panel builders install this type of component during control panel assembly or field replacement of worn push-button operators. It meets a broad set of international certifications including UL 508, CSA C22.2 No. 14, and EN\/IEC 60947-5-1.\u003c\/p\u003e\n\u003cp\u003eThis switch operator is used in industrial and commercial control panel applications where a momentary non-illuminated push-button is required. Typical installations include machine start\/stop stations, conveyor controls, pump panels, and general-purpose operator interface enclosures. The 22 mm mounting hole diameter is a standard industrial form factor widely used across panel-mount operator assemblies. The NEMA 4X rating suits both indoor and outdoor enclosures where washdown or corrosive conditions are present.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e22 mm mounting hole diameter — standard industrial panel cutout size\u003c\/li\u003e\n  \u003cli\u003eMomentary (MO) operation — returns to default position when released\u003c\/li\u003e\n  \u003cli\u003eRound, extended straight-profile blue metal button — nonilluminated\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X and NEMA 13 rated — suitable for wet and corrosive environments\u003c\/li\u003e\n  \u003cli\u003eUL Listed and CSA certified; also meets EN\/IEC 60947-5-1, DNV, GL, RINA, and JIS C 4520\u003c\/li\u003e\n  \u003cli\u003eMetal operator construction for durability in industrial service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation momentary push-button operator for 22 mm industrial control panel assemblies requiring a nonilluminated blue round operator.\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 the enclosure manufacturer guidelines.
