1. An apparatus for providing an electronic signal in response to at least one of an applied force and an applied torque, the apparatus comprising:

  • a base;

    a movable member that provides movement relative to the base in response to the at least one of the applied force and the applied torque;

    a controlling mechanism havinga plurality of resilient mechanisms, connected to the base and co-acting with the movable member, that provide at least one of a restoring force and a restoring torque to the movable member in response to the at least one of the applied force and the applied torque, anda restraining member, disposed within the movable member, that is free of contact with the movable member when the movable member is disposed in a first position, and contacts the movable member to restrain the movement of the movable member relative to the base when the movable member is moved from the first position to a second position in response to the at least one of the applied force and the applied torque; and

    a detection circuit that detects the movement of the movable member relative to the base, and provides the electronic signal.
