Light-controlled plug socket rail; has incorporated electronic control responsive to detected ambient light level for automatic switching of supplied electrical devices

摘要

The plug socket rail (1) has supply sockets (5) for a number of electrical devices has an incorporated electronic control using relays or semiconductor elements and an ambient light level measuring device, e.g. a photocell (3), for switching the electrical devices according to the detected light level, which may be indicated by an acoustic signal source.
