Abstract:
A sensor assembly for sensing relative movement between adjacent panels includes a base and first and second arms pivotally mounted to the base. An electrical connecting element is attached to the first and second arms and holds the first and second arms in a first position to indicate a first condition. When the first and second arms have moved relative to each other by a predetermined amount, the electrical connecting element breaks to indicate a second condition.
