EAO Illuminated Push Button Switch for Use with Series 31, Snap Action, Momentary or Maintained Switching, 16mm 31-122.0252

EAO 31-122.0252 Illuminated Push Button Switch is a robust and versatile component from the EAO 31 series, engineered for use in various industrial and process control applications. It is optimized for human-machine interface (HMI) panel mounting, commonly found in machinery, instrumentation, and panel building environments where precise control and reliable switching are required.

The switch features options for round, square, or rectangular bezels with an 18mm diameter or sizes up to 18x24mm. It offers snap action or low-level switching elements, providing users with choices between momentary or maintained switching actions to fit specific use cases.

The snap action element ensures a self-cleaning, double-break contact system with solder terminal connections, making it suitable for general-purpose switching. The low-level switching element caters to low power electronic circuits with current ranges from 10μA at 100μV up to 100mA at 42Vac/dc, featuring universal terminals for soldering or PCB mounting.

Illumination options include a T1 ¾ midget groove filament lamp or a single chip LED, both supporting voltages between 6 and 48V. For applications requiring voltages above 48V, an external series resistor is required to maintain operational safety and performance.

The push button requires a 16mm panel cut-out and is compatible with panel thicknesses ranging from 1.5 to 6mm. Its construction includes a raised button profile and self-extinguishing housing materials, meeting Class II safety compliance.

Electrical endurance is validated with an electric strength of 2500Vac at 50Hz for 1 minute between terminals and earth, conforming to IEC 60512-2-11 standards. This ensures safe and reliable operation in industrial environments.

Accessories such as lenses, filament lamps, LEDs, and tool kits are available separately to complete a functional illuminated push button setup. Compatible with Series 31 panel mounting applications. Available with snap action or low-level switching elements.
