Abstract
A multi-stage capacitive sensor is provided having a layered structure, including a user-contact surface, a first capacitive sensor for the user-contact surface, a second capacitive sensor which is spaced apart from the first capacitive sensor in a direction away from the user-contact surface, and a conductive member. The conductive member is positioned between the first and second capacitive sensors, and is engaged with the first circuit substrate and spaced apart from the second capacitive sensor. In a preferred embodiment, under the application of a force at the user-contact surface, the conductive member is deflected relative to the second capacitive sensor to alter a distance therebetween to create a detectable change in a capacitance at the second capacitive sensor.
