Claim of US Patent No. 9,967,374

1. A mobile phone, comprising:a circuit board having a processor thereon; and
a chassis shell having an integral unibody including a co-mold loop feature surrounding a button profile feature, the co-mold loop feature and the button profile feature located on the surface of the chassis shell, the co-mold loop feature preventing an independent movement of the button profile feature, wherein the co-mold loop feature is integrally bonded to both the button profile feature and a passive part of the chassis shell surrounding the co-mold loop feature;
a channel formed within the chassis shell defining the co-mold loop feature and electrically insulating the button profile feature from the chassis shell; and
a sensor system coupled to the circuit board and the button profile feature from an interior side of the chassis shell, wherein the sensor system is configured to detect a user interaction event based on sensor readings from the sensor system and to register the user interaction event with the processor.
