Abstract

A sensor for use in an interactive electronic device. The sensor is operative to generate a plurality of different output signals corresponding to respective positions of the sensor relative to a reference plane. The movement of the sensor relative to the reference plane facilitates the movement of one or more actuation balls of respective switches of the sensor, which in turn results in the generation of differing conditions or output signals corresponding to closed or open circuit conditions selectively created by the switches.
