The Accuratus 540 from Ceratech has an A4 footprint and an in-built touch pad for those applications where space is limited, such as rack server draws. A big winner with major retail stores, this beautifully constructed keyboard offers all the facilities of a grown up board but with some of the ‘fat’ remove. Though smaller than a standard keyboard, the 540 is still very tough using reliable membrane technology and laser etched keys which ensures the characters remain fresh throughout the products life. Small, tough & reliable – It’s got to be the 540
