The ALFW29920D-G-24V is an illuminated 22mm pushbutton switch with extended lens and full shroud design, configured with 2NO (two normally open) contacts for momentary operation. This switch features a transformer-based lamp circuit rated at 24V, providing reliable illumination in industrial control panels. The device incorporates IDEC's TW Series design with snap-on contact blocks, self-cleaning contact mechanisms supporting a wide current rating from 5 mA to 10 A, and a corrosion-resistant octagonal chrome-plated locking bezel. The switch is housed in fracture-resistant nylon with M3.5 terminal screws and accommodates panel thicknesses from 1 to 6 mm. Typical applications include emergency stop systems, machine control interfaces, and industrial automation where visual feedback and reliable switching are essential.
