US90-30 Jumbo Publication Number: PB3018 DEC/11 Dewhurst US90-30 Jumbo Pushbutton The US90-30 Jumbo Pushbutton is a classic square extra large button which meets all the requirements of the visually impaired. As well as the 30mm high tactile legend, Standard English Braille dots are embossed onto the pushbutton. The button was primarily designed for use in larger buildings such as hospitals, airports and shopping centres, where the sheer scale of the building necessitates a larger button. On call acceptance the large 30mm high legend illuminates brightly and you have the choice of many colour options. The US90-30 Jumbo has an identical appearance to the standard US90-15 and so the two buttons can be used on faceplates together when appropriate.
