Structure and inner electrical connection
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
The signal is converted by a Piezo-ceramic disc. Pressure forces within the ceramic lead to a load shift that causes a voltage.
This voltage is picked up by contact discs.
