Series 84 "Halo Illumination" PCB Switch



Offered by:

EAO Corporation


Series 84 "Halo Illumination" PCB Switch Description:

EAO, the Expert for Human Machine Interfaces, is now offering a switch with multicoloured “Halo” illumination for creating highly flexible displays. Designed for use with SMD LEDs, up to 10 different colours can be combined in one switch: eight within the outer ring and an additional bi-colour LED in the centre. For designers and developers, this opens up new and previously unimagined possibilities.

Key characteristics:

  • Segmented illumination of the outer halo ring (actuator)
  • Up to 8 SMD LEDs can be positioned on the PCB *
  • Additional bi-colour LED can be used with the switch element
  • Flat or raised plastic or aluminum lenses


The transparent actuator is mounted on the PCB by means of a newly developed flange with snap-on connector. The switch mounts into a 22.5 mm dia. mounting hole.

Typical applications:

  • Ticket machines
  • Instruments and medical devices
  • Machine and process controls
  • Audio, video, general lighting and stagecraft

Switching system:

Single-interrupting snap-action switch system with two independent contact points and tactile switching point. Secure switching even in the case of minimum operational data. Contact mounting: one normally-open contact.

Environmental conditions:

  • Storage temperature -40 °C ... +85 °C
  • Operating temperature -25 °C ... +70 °C
  • Type of front protection IP67 (IEC 60529)
