Zusammenfassung:	A safety circuit for deenergizing an electric blanket of the type utilizing a positive coefficient resistance material as the heating element positioned between a pair of spaced conductor wires. The circuit includes one or more gas tubes with parallel resistances connected across the conductor wires to sense voltage changes caused by open or short circuits and to conduct sufficiently high currents to blow a series connected fuse.
