Capacitive Touch Switch for Automotive Applications 6

Warning! When you recommend this feature to management, some people (most likely from the marketing department) will express concern that people will not be able to unlock the car when the windows are rolled down. The application of CapSense switches is not limited to the interior of automobiles. The door handle sensor is an ideal example. For this application, a metal handle is used as a sensor. Make the sensor highly sensitive for use as a proximity detector. When a hand gradually approaches the car door, power will be applied to the safety hardware that requires much higher power. As part of the car alarm system, the result can be recorded and the owner notified that someone has repeatedly attempted to approach the car door handle. (It is even possible to call the car owner's phone.) Due to the lack of mechanical components and the ability to easily match various surfaces, touch sensitive capacitor switches are considered an ideal technology for today's automotive applications. They are a cost-effective alternative to traditional switches and enable designers to achieve novel and innovative customer panel functionality.  diode
