Busstop Switch ZF

Bus Stop Buttons Are Now Wireless & Battery-Free

Auerbach. Thanks to the wireless and battery-free switch technology from ZF, there are various possible application fields to increase connectivity, flexibility, and convenience. Bus stop buttons are another smart application integrating the inductive RF generator module. The target is to avoid cabling (up to 100m) and expensive maintenance work caused by cable breaks in buses. The energy harvesting switch guarantees design freedom and reduces maintenance work to a minimum as it has a lifetime of over 1,000,000 switching cycles.

The energy harvesting switch can be integrated directly into the plastic housing of the stop request buttons in buses. The compact design (20.1 x 7.3 x 14.3 mm) makes it easy to integrate. In addition, the ZF radio switch generates a voltage pulse by mechanical actuation as it relies on the inductive principle. Therefore, RF commands can be reliably sent via commercially available radio protocols such as EnOcean3.0 at a frequency band of 868MHz. In this case there is no risk of RF interference with Bluetooth devices which operate at a 2.4 GHz frequency range. Altogethe
