SENSOR ASSEMBLY AND DISPLAY INCLUDING A SENSOR ASSEMBLY
First Claim
1. Sensor assembly including a coordinate input surface and, under a region of the surface,at least a first switch assembly and a second switch assembly, each including at least a first conductive element and a second conductive element, the second conductive element being movable relative to the first conductive element,the first and second switch assemblies and their respective first and second conductive elements being arranged so that:
- when no force is exerted on the region of the surface or when a force smaller than a first threshold force is exerted thereon, the first and second conductive elements of the first switch assembly are not in contact with each other and the first and second conductive elements of the second switch assembly are not in contact with each other;
when a force larger than the first threshold force and smaller than a second threshold force is exerted on the region, the first and second conductive elements of the first switch assembly are in contact with each other and the first and second conductive elements of the second switch assembly are not in contact with each other; and
when a force larger than the second threshold force is exerted on the region, the first and second conductive elements of the first switch assembly are in contact with each other and the first and second conductive elements of the second switch assembly are in contact with each other.

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.
