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.
