Abstract
A contact monitoring means for monitoring an electrical, three-pole changeover contact includes: a signal generator, which generates a monitoring signal; a coupling means, which is connected downstream from the signal generator; a sensing circuit, which is connected downstream from the coupling means and which is coupled or can be coupled to the changeover contact. The monitoring signal generation of the signal generator and thus the monitoring signal and/or a signal derived from the monitoring signal can be changed as a function of a switching position of the changeover contact by means of the sensing circuit, which is coupled to the signal generator via the coupling means. The contact monitoring means also includes an evaluation means, which detects the monitoring signal and/or the signal derived from the monitoring signal and/or a change of the monitoring signal and/or a change of the signal derived from the monitoring signal.
