Abstract
The disclosure relates to a method for predicting the failure of an elementary relay having a switch for switching a load contact of a load circuit and an excitation coil for actuating the switch. The method may include exciting the excitation coil in order to switch on the load contact; detecting a time characteristic of a contact voltage at the load contact when switching on the load contact; extracting a characteristic feature from the time characteristic of the contact voltage; and monitoring the characteristic feature during operation of the elementary relay.
