Abstract

1,136,358. Analogue - to - digital converters. INTERNATIONAL RECTIFIER CO., (GREAT BRITAIN) Ltd. 25 Oct., 1967 [31 Oct., 1966], No. 48705/66. Heading G4H. A device for indicating the level of current flowing in a conductor 15 comprises a number of reed switches 10-13 arranged to operate at different levels of current in the conductor in response to the magnetic field generated, and an electric indicator 30-33 associated with each switch. The reed switches may be placed at different distances from the conductor as shown, or alternatively they may have different operating characteristics or be differently orientated. The indicators may be lamps.
