EAO Offers Series 56 Door Opening Pushbuttons that Meet TSI-PRM Standards

Milford, CT - EAO Switch Corporation of Milford, CT USA, a premier global supplier
of Human Machine Interface (HMI) Components and Systems, announces a new addition to their internationally recognized Series 56 door opening pushbutton - raised and illuminated open/close symbols. The switch, along with the Series 56 switch series, meets European Technical Specifications of Interoperability for Persons with Reduced Mobility (TSI-PRM) standards and increases passenger awareness by heightened visual indication when used with other ADA components.

This addition to the Series 56 pushbutton features symbols that are raised more than 1mm from the surface and are larger than 15mm wide, for improved usability and visibility for disabled passengers. It also features a brightly lit and highly recognizable 'Door open' or 'Door close' symbol to aid passengers finding the door control more easily. Additional luminance is provided by a bright LED halo around the pushbutton's actuator - green, blue, or yellow. A large thermoplastic bezel available in many colors is fitted around the actuator to provide visual contrast with the surface on which it is mounted. These bezels are also available with Braille legends additionally assisting visually impaired individuals. As well, low actuation force, short travel, and snap action contacts offer good tactile feel to further support disabled users.

Series 56 pushbuttons operate in extreme temperature conditions from -49º up to +176ºF. They are environmentally sealed to IP 67 at the front and to IP 65 in the rear of the switch, RoHS approved, and meet many of the required international electrical standards. All materials used meet the rail industry's expectations of quality, reliability, durability, and design. The new version matches the design and dimensions of previous, and can be retrofitted into the existing mounting holes. EAO is International Railway Industry Standard (IRIS) certified.
