31-455.036, EAO Push Button Switch for Use with Series 31 Push Buttons, Кнопочный переключатель

Illuminated Push Button Switch - EAO 31 Series

The EAO 31 series of illuminated push button switches are suitable for use in many Human Machine Interface (HMI) panel mounting applications including Process Control, Panel Building, Machinery and Instrumentation. The illuminated push button switches are available in a choice of round (18mm diameter), square (18x18mm) or rectangular (18x24mm) bezels with snap action or low level switching elements with momentary or maintained switching actions.
The snap action switching element is a self-cleaning, double-break, snap action system with solder terminals, while the low level switching element is designed for switching low power loads in electronic circuits ranging from 10μA at 100μV up to 100mA at 42Vac/dc, termination is via universal terminals that allow either direct soldering or PCB mounting.
Illumination for the EAO 31 series of push button switches is via a T1 midget groove filament lamp or single chip LED with a voltage of between 6 and 48V. For supply voltages above 48V, it is necessary to use an external series resistor.
All EAO 31 series of illuminated push button switches require a 16mm panel cut out and are suitable for panels with a thickness of between 1.5 and 6mm. They have a long life, short rebound time and a stable contact resistance.

Various configurations available including low level or snap action elements, momentary or maintained switching actions and normally closed or normally open contacts
Raised button profile
Self-extinguishing switch and actuator housing material
Class II compliant
Electric strength 2500Vac 50Hz for 1 minute between all terminals and earth, as per IEC 60512-2-11

EAO Push Button Switch, 100mA Switching Current, 16mm Cutout Diameter - 31 Series - 31-455.036

Use this push button switch from EAO to control your HMIs. The component's momentary switching action means the switch activates whenever you press it and deactivates when released, making it suitable for short-term operations. It has compact front dimensions of 18 (length) x 18mm (width) and needs a cutout size of only 16mm, so you can easily install it where space is limited. The switch's gold-plated silver contacts are highly conductive and corrosion-resistant, giving you a reliable connection. A light weight of 7g means it won't place too much strain on your equipment. The button has a low switching current of 100mA, so it's an energy-efficient choice.

Features & Benefits

• Plastic housing is resistant to corrosion and wear for durability
• Snap-action mechanism for quick switching
• IP40 rating means it's finger-safe and protected from tools and wires larger than 1mm in size
• Broad operating temperature range of -25°C to +55°C for use in challenging conditions

Applications

• Door buzzers
• Arcade gaming consoles

How do I install this component?

You can solder this component directly onto your PCB, giving you a secure and vibration-resistant connection to your equipment.
