Industrial 2ALF3LB-110 Industrial Relay Module

2ALF3LB-110 is a 22 mm flush-mount illuminated pushbutton switch from Altech Corporation, built for momentary actuation with green LED illumination and a 110 V AC/DC rating, making it a compact, visible input for control panels and industrial equipment. This device belongs to Altech’s 22 mm pushbutton family and features a round, green-lit indicator with a flush head designed for panels where a low-profile, clean appearance is important. It is specified as a momentary switch, so the contact returns to its resting state when the actuator is released, and it carries a 110 V voltage rating suitable for either AC or DC configurations depending on the exact variant. The 2ALF3LB-110 is commonly used as a manual control input in machine controls, control stations, and panel assemblies where a clear green status cue is desirable for start/stop or enabling functions. Verified listings from major distributors—Digi-Key, Mouser, and Jameco—confirm the part number ALF3LB-110, green illumination, flush 22 mm form factor, momentary action, and 110 V rating, underscoring its suitability for 110 V control circuits and panel installations. This combination of compact size, illuminated feedback, and simple momentary operation helps operators quickly identify an active control point while keeping wiring and footprint minimal.
