摘要：
The invention relates to a self-testing proximity switch, wherein the testing is carried out with the aid of bipolar double pulses which, independently of the switching state of the trigger stage, each time cause a short-timed triggering thereof. At the output of the trigger stage, the superimposed pulses can be evaluated by the test circuit in order to monitor proper functioning of the proximity switch.
