Visually impaired can benefit from blue illuminated keypad

29 June 2005 Switches, Relays & Keypads

For engineers designing keypads into applications for disabled users, EAO offers a new option of bright blue key illumination, generated from high quality LEDs. This is now available in EAO's popular S.series keypad range.

Visual impairments, which often include the inability to distinguish between the colours red and green, can result in problems for users operating keypad-driven devices. EAO's easy to read, blue-illuminated S.series keypad is also available with a 'blind pin locator' which can be found on key 5, together with raised characters including 'o' and 'x'.

EAO also offers full keypad customisation services including solutions for full colour front plate designs as well as laser engraving and marking. The visually impaired may also benefit from the 'Tiresias' font option, which has been specifically designed to aid legibility.

Available with either 12 or 16 keys, and in a choice of standard, telephone, or hexadecimal II configurations, the S.series keypads feature a front plate and anti-pull-off keys made of Zamak, that delivers a high level of vandal-resistance. It is tested to 4 million operations and is protected to IP67.

The aesthetic, rugged and robust features of the S.series makes it well-suited for public environment applications including access control, banking, public telephones, vending machines and industrial machinery, etc.
