ABSTRACT:
A circuit arrangement includes a wear detector which is proportioned or which operates so that it wears (i.e., fails) faster than the other parts of the circuit arrangement. The wear detector may be made to wear faster than other parts of the circuit by being more heavily loaded during operation, by being configured to be more heavily stressed during operation, or by being subjected to more severe operating conditions. An indicator is connected to the wear detector so that, when the wear detector ceases to function, the indicator signals that the circuit arrangement is near the end of its useful life and is to be replaced.
