Product Description
The EAO 31-121.0252 is an illuminated push button switch designed for use with the Series 31 range, operating at a maximum switching voltage of 250V AC. It provides momentary switch action ensuring activation only during pressing, suitable for precise control in industrial automation applications.
This momentary push button is equipped with gold-plated silver contacts, ensuring high conductivity and resistance to corrosion for reliable electrical performance over time. The contacts are self-cleaning, minimizing maintenance by preventing dirt accumulation.
The switch includes provision for a T1 ¾ midget filament lamp or an LED illumination (6-48V supply), allowing clear visibility on dense control panels. It requires a 16mm panel cutout and supports mounting on panel thicknesses of 1.5 to 6mm. The IP40 rating affords protection from solid particles larger than 1mm, making it suitable for a variety of industrial environments.
Solder terminals secure wiring connections and are engineered to withstand vibrations, maintaining consistent operation. Applications include automated door controls, office building systems, and agricultural machinery, making it versatile for human machine interfaces in process control, panel building, and instrumentation.
Note that an LED and lens cover (Distrelec 248-5396) are required to complete the assembly for illumination functionality. The switch’s compact size and robust construction make it an ideal component for reliable, long-lasting panel-mounted control solutions.
The switch uses momentary action for precise control. Gold-plated silver contacts improve conductivity and durability. Self-cleaning contacts reduce maintenance needs. IP40 rating protects against solid objects larger than 1 mm.
16mm cutout diameter enables easy mounting on panels. Solder terminals provide secure electrical connections. Applicable to automated doors, office, and agricultural equipment. Requires additional LED and lens cover for illumination.
