It features a 22 mm mounting hole diameter, a round green metal extended (straight) push button, and an integrated LED lamp for operator status indication. The maintained (MA) operation type means the switch holds its state after each press, making it well-suited for on\/off control functions. Licensed electricians and control panel builders install this switch as part of machine control, automation, and process equipment assemblies. It carries NEMA 4X and 13 ratings, confirming suitability for wet, dusty, and corrosive environments.\u003c\/p\u003e\n\u003cp\u003eThis push-button switch is used in commercial and industrial control panels, automation enclosures, and machine operator stations where a maintained-contact, illuminated switch is required. The green button color follows common industry convention for run or start functions. Its NEMA 4X rating makes it appropriate for wash-down environments and outdoor enclosures. Electricians and panel integrators specify this switch for applications requiring a durable metal operator with integrated LED indication and compliance with UL 508 and IEC 60947-5-1 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaintained (MA) operation holds switch state after each actuation\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED lamp provides clear operator status indication\u003c\/li\u003e\n  \u003cli\u003e22 mm mounting hole diameter fits standard industrial panel cutouts\u003c\/li\u003e\n  \u003cli\u003eRound green metal extended push button with corrosion-resistant construction\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X and 13 rated for wet, dusty, and corrosive environments\u003c\/li\u003e\n  \u003cli\u003eCertified to UL 508, UL Listed, CSA C22.2 No. 14, EN\/IEC 60947-5-1, and multiple 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 push-button operator for 22 mm industrial control panel assemblies where maintained-action illuminated switches are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the control panel and verify zero voltage before removing or installing any switch operator. Ensure the panel cutout matches the 22 mm mounting hole diameter before mounting.
