EAO, the expert in Human Machine Interfaces, explains how switches can improve train reliability and passenger access

Refurbishment projects are an opportunity to enhance an old vehicle’s value and enable it to compete in the lease market. Switches play an important role in these projects because they can improve reliability and ensure compliance with new regulations about passenger access.
Old interior switches with filament-lamp illumination used in driver’s cabs and on doors can undermine reliability because the lamps fail more frequently than LEDs. Vibration and shock from the train’s movement often causes them to blow, resulting in costly and unscheduled maintenance. LED’s also use less power and generate less heat, making them a safer, more economical option. EAO has a wide range of LED-illuminated products.
The right switches are important for passenger door access, particularly where disabled users are concerned. The Rail Vehicle Accessibility Regulations (RVAR) are influential on the design of interiors. Switches need to be fitted at certain heights, operable by palm and identifiable by touch. EAO have manufactured their Series 56 pushbutton around the RVAR and can advise on installation.
EAO is also a specialist in engineering complete control panels for refurbishment projects. We can deliver fully-wired units in high or low volume in order to meet a precise refurbishment schedule.
