The Challenge

In today's automobiles, a single click of a button or switch is used everywhere, including starting the engine, dashboard controls for entertainment and diagnostic information, and advanced door locking systems. This makes it critical to test the functionality of buttons and switches as the risk of a defective button could be very high, the driver not being able to enter or turn on the vehicle. Mechanically testing buttons is mainly compression testing to understand how much force is required to push a button to engage the electrical signal. This is also known as tactility testing of buttons where OEMs are interested in testing to determine the "feel" of a button.
