Description
The Automatic Shut-Off is a safety system which
turns off the electrical power of a load based either
on a movement detection or a position detection.
This detection will be taken into account after a well
defined time delay. A typical application is the safety
feature in irons which will switch off the heating
element when the iron is left immobile for a well
defined period, which can be dependant on the
position. The state of the Auto Shut-Off can be
indicated with an led.
