ABSTRACT:
An immersion detector comprises a pair of spring biased circuit breaking contacts for removing power from an appliance. The appliance has a sensing circuit which may become energized if it is dropped into a body of an electrically conductive liquid, such as a sink full of water. An SCR is connected to each side of the line and is triggered by an energization of said sensing circuit so that it is irrelevant which side of the line is hot and which side is at neutral. When either SCR conducts, a solenoid releases the spring bias which causes the circuit breaking contacts to fly apart.
