In a method for function monitoring of an electronic-mechanical position switch in which the wiper voltage of a potentiometer acted upon by an actuation tappet is evaluated in comparison to a threshold value in order to activate or deactivate electronic contacts, during first or second test intervals a microcontroller interrupts watchdog signals or contact-closing control signals and checks the state of the switching contacts. If the expected state transition of the switching contacts from the closed into the open state does not occur, then the control signals make the transition to the contact-opening signal level or the watchdog signals are discontinued.

Method and circuit arrangement for function monitoring of an electronic-mechanical position switch

A modular electrical device combination includes an operator control module and a computer module that can be electrically coupled to the operator control module. The operator control module has a fastening portion on its rear side for installation into a mounting panel. Mechanical connecting means are provided in an extension at a free end of the fastening portion.
