摘要:
A key activation system for use in an electronic device is provided. The system comprises an activation mechanism associated with a key in the system, a first feedback system and a second feedback system. The activation mechanism is associated with the key activation system and provides a first feedback sense when the activation mechanism has triggered the first activation condition. The second feedback system provides a second feedback sense indicating when the key triggers the second activation condition. In the system, the second feedback system operates independently from the activation mechanism and the first activation condition is triggered before the second activation condition when the activation mechanism is initially engaged. An activation mechanism may be centrally located for a set of keys.
