S u m m a r y: Safety Switching Means for Controlling a Current Consumer The safety switching means comprises a source of radia- tion (21) which is switched on and off periodically. Only in the event that radiation (22) was detected by the de- tector (6) when the source of radiation (21) is switched on, it will be checked - with the source of radiation (5) switched off - whether the detector (6) is applied by ra- diation (22) nonetheless, and, in the event of no radiation being found by the detector (6), the current consumer will be switched on automatically by the switching means, since it is certain that the hand of a user covers the window (4).
