Proximity sensor assembly having interleaved electrode configuration

摘要

A proximity switch assembly and method for detecting activation of a proximity switch assembly is provided. The assembly includes a plurality of proximity switches each having a proximity sensor providing a sense activation field. A first proximity sensor generates a first activation field and comprises first and second electrodes having first fingers interdigitated with second fingers. A second proximity sensor generates a second activation field and comprises third and fourth electrode fingers having third fingers interdigitated with fourth fingers. The first and second electrodes are interleaved with the third and fourth electrodes.
