Help points, passenger call buttons and door release for stations.
Platform controls, ticket machines, information displays, and shelter systems in train, bus, and metro stations face continuous public use, weather exposure, and vandalism. RNC solid-state interfaces provide the durability and reliability that transport station infrastructure requires. RNC piezo switches meet that same standard for platform and shelter controls.
Help point, passenger call button, emergency call button, door open button.
Help point columns anchor station platforms end to end, giving passengers and staff a single point of contact with a control room the moment something goes wrong. Passenger call buttons and emergency call buttons sit at intercoms throughout the station: on platforms, at ticket halls, in lifts and stairwells, built as solid-state piezo switches with no moving parts, so a press registers the same way after ten years as it did on the first day of service.
The same platform supplies door open buttons and stop request buttons fitted inside trains and buses, where a single button is touched thousands of times a day by passengers who are cold, wet, gloved or simply in a hurry. A raised symbol and backlit illumination make each button easy to find and confirm by touch or sight, without relying on moving parts that wear, stick or fail under constant everyday use.
Sealed against washdown cleaning, weather and vandalism, these buttons have accumulated decades of public use across station and bus stop networks worldwide. RNC's piezo switches and piezo keypads share the same sealed, solid-state foundation, so a single supplier covers help points, call buttons, door controls and ticket machine entry across an entire station.
