Stop-request pushbutton

The Series 84 stop request pushbutton for public transportation meets the PRM TSI directive (Persons of Reduced Mobility Technical Specification for Interoperability).

The pushbutton has raised symbols for passengers who are visually impaired, and an LED-illuminated halo that provides a visual indication for hard-of-hearing passengers. LEDs are available in red, orange, yellow, green, blue, or white. The device can be pole or panel mounted in a contoured housing.

The tactile feedback of the short-travel switching system operates at the slightest touch (typically six to 12 Newtons) and provides positive tactile feedback to passengers. Symbols are raised 1 mm from the aluminum lens surface and are greater than 18 mm wide.

The shock, vibration, and climate-resistant pushbutton is sealed to IP67. It uses a high-quality, normally open contact of gold-plated silver alloy rated 10 µA – 100 mA, 50 m Vac/Vdc – 42 Vac/Vdc. Under optimal operating conditions, it will last for at least 1 million activations.
