Abstract

The object of the invention is to extend, by simple means and in economical fashion, a radiation-sensitive switch which, in its usual design, has a maximum coverage angle of 180 DEG in the horizontal plane. To achieve this, at least two detector casings (1) housing an optical recording system are disposed in pivotable fashion in relation to one another, and the second optical recording system is in each case aligned so that it covers an area not monitored by the first optical recording system. The invention is preferably used for area surveillance with the aid of infrared detectors. <IMAGE>
