Abstract

A controller for selectively adjusting a power seat includes a seat adjuster including a base panel, a stepped panel extending laterally from a surface of the base panel, selector areas inclined with respect to and extending between the base panel and the stepped panel and along at least a portion of a periphery of the stepped panel. Multiple spaced depressions are formed on an outer surface of the selector areas. A contactless sensor is secured to an inner surface of the selector areas at each a depression, each sensor selectively producing a signal representing a seat adjustment function.
