2 Push Buttons

Push buttons can be found in both the center infotainment display and the steering wheel on a car. These buttons can be used for many different applications, including media controls, air conditioning, cruise control, or even as a button to detect the end user activating the car horn. Implementing these push buttons can be done with various technologies such as mechanical switches, magnetic switches, capacitive touch, or inductive touch solutions.
