ABSTRACT:
An automatic power shut-off circuit for a wide variety of electrical appliances, such as hand-held hair dryers, razors, irons, hair curlers, etc. which pose a risk of electrocution when used around water. Thus, said circuit avoids the risk of dangerous shocks or even death, if the appliance should fall into a tub of water in which someone is bathing or if someone reaches or steps into water containing a plugged-in appliance, regardless of whether the switch of the appliance is on or off.
