Abstract
A sensor assembly includes a coordinate input surface and, under a region thereof, a first and second switch assembly. Each assembly includes at least a first and second conductive element. When a force smaller than a first threshold is exerted on the surface, the first and second element of both assemblies are not in contact with each other. When a force larger than the first threshold and smaller than a second threshold is exerted, the first and second elements of the first assembly are in contact with each other, while the elements of the second assembly are not. When a force larger than the second threshold is exerted on the region, the elements of both assemblies are in contact with each other. A display including a sensor assembly is also disclosed.
