Abstract
A proximity switch assembly is provided and includes a proximity sensor comprising a first electrode comprising first fingers and a second electrode comprising second fingers, wherein the first and second fingers are interdigitated with a varying density and a variable spacing therebetween along a first direction. The proximity switch assembly also includes control circuitry processing a signal in response to a user activation of the proximity sensor and determining sliding activation of the sensor in the first direction. The switch assembly may determine a tap, stable press and sliding activations.
