ABSTRACT:
An alarm system for automobiles, which is actuated when an unauthorized person tampers with the automobile. An inductive coupling is made with the automobile electrical system so that a variation in current flow in the system activates the alarm. An actuating switch of the reed type is made operative by the driver utilizing a magnet. A deenergizing switch, of the reed type, located remotely from the actuating switch is used to make the system inactive at the driver's option. An auxiliary reed type switch is located adjacent the deenergizing switch and activates the alarm if an unauthorized person attempts to use the deenergizing switch.
