It features a 22 mm mounting hole diameter, a flush-style rectangular actuator in black and white, and an integrated LED lamp for operator feedback. The bezel is constructed from chromium-plated metal, providing durability in demanding environments. Rated NEMA 13 and 4X, this switch resists dust, oil, and corrosive agents, making it suitable for washdown and harsh-duty installations. Licensed electricians and control panel builders are the primary installers of this device.\u003c\/p\u003e\n\u003cp\u003eThis push-button switch is used in industrial control panels, machine operator interfaces, and process control equipment where a momentary on-off switching sequence with visual indication is required. The LED illumination allows operators to confirm switch activation or system status at a glance. Its shock-resistant and vibration-resistant construction suits applications in manufacturing, automation, and heavy equipment environments where panel-mounted controls are subject to mechanical stress.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e22 mm mounting hole diameter for standard industrial panel cutouts\u003c\/li\u003e\n  \u003cli\u003eMomentary (MO) operation with on-off switch sequence\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED lamp provides illuminated operator feedback\u003c\/li\u003e\n  \u003cli\u003eFlush, rectangular actuator in black and white\u003c\/li\u003e\n  \u003cli\u003eChromium-plated metal bezel for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eShock-resistant and vibration-resistant construction\u003c\/li\u003e\n  \u003cli\u003eNEMA 4X and NEMA 13 rated for washdown and oil-tight environments\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 switch for industrial control panels requiring a standard 22 mm momentary illuminated switch with LED indication.\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 applicable local codes.
