Abstract

607,992. Current detectors. JUSTESEN, C. A. Feb. 13, 1946, No. 4521. [Class 37] A device for testing for faults in electric circuits, particularly on motor cars, comprises a casing 1 of conducting material pointed at one end so that a pin 2 is formed which can be inserted into the covering of a conductor to be tested. Inside the casing is a lamp 3, one pole of which is connected to the casing, while the other pole is in contact with a metal disc 4 at one end of a conductor 5 which passes through a screw plug 6. The disc 4 is embedded in an insulating bush 8 pressed towards the lamp 3 by a spring 9. The other end of the conductor 5 carries a spring clip which can be attached to the frame of the car. Holes 11 in the casing 1 permit observation of the lamp 3.
