It features a red, round extended mushroom head operator machined from metal, and mounts through a 22 mm panel cutout. The switch is non-illuminated and returns to its original position immediately upon release, making it well suited for stop, emergency-reset, or momentary-command functions. It carries a NEMA 4X and NEMA 13 enclosure rating, indicating resistance to washdown, dust, and corrosive environments. Licensed electricians and control panel builders install this switch in accordance with NEC and applicable local electrical codes.\u003c\/p\u003e\n\u003cp\u003eThis switch is used in residential, commercial, and industrial control panels where a momentary operator is required. The 22 mm mounting diameter is a widely adopted standard in industrial pushbutton and selector switch assemblies. The extended mushroom head profile makes it easy to locate and actuate quickly, which is common in machine control, pump control, and process equipment panels. The metal construction suits demanding environments where plastic operators would be subject to wear or chemical exposure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e22 mm mounting hole diameter fits standard industrial control enclosure cutouts\u003c\/li\u003e\n  \u003cli\u003eMomentary (MO) operation — returns to off position on release\u003c\/li\u003e\n  \u003cli\u003eRed extended mushroom head operator for fast visual identification and actuation\u003c\/li\u003e\n  \u003cli\u003eMetal push-button construction for durability in harsh environments\u003c\/li\u003e\n  \u003cli\u003eNon-illuminated operator — no internal lamp or LED required\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X and NEMA 13 rated for washdown, dust-tight, and corrosion-resistant applications\u003c\/li\u003e\n  \u003cli\u003eCertified to UL 508, 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 momentary push-button operator for 22 mm industrial control panel assemblies.
