Abstract
A method of detecting a switching state of a switching contact of an electromechanical switching device, the switching contact having at least one pair of contacts, during an operating phase for detecting the switching state, includes: applying a switching current to the switching contact; and analyzing the switching current using an evaluation unit to determine whether the switching contact is in a closed switching state or in an open switching state. A switching current in a form of a clocked voltage or current signal is applied to the switching contact.
