This operator-only component features a black, non-illuminated round handle head with a 22 mm panel cutout diameter. It uses a maintained (MA) operation type, meaning the switch holds its selected position until manually moved. The plastic bezel construction is shock-resistant and vibration-resistant, and the unit carries IP66 and IP69K ingress protection ratings, making it suitable for wash-down and high-moisture environments. Licensed electricians and control panel builders install this component as part of a complete 22 mm selector switch assembly.\u003c\/p\u003e\n\u003cp\u003eThe ZB5AJ3 is used in 22 mm control panel installations across industrial, commercial, and marine environments. Its IP66 and IP69K ratings make it appropriate for food and beverage processing, water treatment facilities, and other applications where high-pressure wash-down or water ingress is a concern. The 3-position configuration is commonly used for hand-off-auto (HOA) or similar multi-mode selector circuits. Because this is the operator head only, it must be paired with a compatible contact block or switch body to complete the assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-position maintained operation holds position without spring return\u003c\/li\u003e\n  \u003cli\u003e22 mm round head fits standard 22 mm panel cutout diameter\u003c\/li\u003e\n  \u003cli\u003eIP66 and IP69K rated for wash-down and high-moisture environments\u003c\/li\u003e\n  \u003cli\u003eNEMA 13 and 4X rated for indoor and corrosion-resistant applications\u003c\/li\u003e\n  \u003cli\u003eNon-illuminated black plastic bezel with shock-resistant and vibration-resistant construction\u003c\/li\u003e\n  \u003cli\u003eMeets 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 operator-only component for 22 mm modular selector switch assemblies.
