Capacitive Touch Switches for Automotive Applications

Last Updated: 
Aug 03, 2012

Today's cars have far more switches and buttons than earlier models. Not only are there more, but they also need to be easily installable into increasing more contoured control surfaces. They also have to be cost effective, ruling out hermetically sealed switches. One approach gaining momentum is to convert to capacitive touch switches (cap sense). With no mechanical parts, as well as the ability to conform to contoured surfaces, cap sense switches provide the reliability and cost point required by the automotive industry. This article looks at how to implement capacitive sensing interfaces in automotive applications.
