摘要：

A three-axis gravity switch having a curved chamber to retain a gravity responsive member such as a ball of liquid mercury, the chamber having a three-dimensional pathway defined on at least one of its walls, where the gravity responsive member and pathway are conductive, either electrically or optically, such that a circuit is completed when the gravity responsive member contacts the pathway, where the switch can be rotated, inverted and translated in three dimensions such that the pathway defines an acceptable three dimensional course of rotation for the switch.
