ABSTRACT:
A switch assembly includes a central first switch with a concave surface, a plurality of second switches adjacent to and surrounding the central switch in an elliptical or circular shape, where the second switches form a convex surface, and a plurality of third switches adjacent to the second switches in an outer side of the elliptical or circular shape of the second switches, where the third switches include activation areas with concave surfaces and with flat surfaces outside the activation areas. The third switches can include two switches, one of which is located at one end and the other one of which is located at the opposite end of the elliptical or circular shape of the second switches. The non-planar surfaces of the switch assembly enable one to easily feel the locations of the switches and to get tactile feedback when the finger moved to another switch area.
