ABSTRACT:
A time limited signal conduction switch 13 powered by an internal energy source 16 with a given life span. A lithium inorganic cell 16 is used as the internal energy source and is coupled to a specially designed switch 13 which allows signal conduction for a predetermined period of time. The life span of the switch 13 will be limited by the current drain on the battery 16.
