Abstract

1,046,211. Thyristor switching circuits. BIRMINGHAM SMALL ARMS CO. Ltd. March 24, 1965 [April 16, 1964], No. 15708/64. Heading H3T. [Also in Division H2] A circuit for controlling the current flowing in a load 10 amplified from an A.C. supply 1, 2 comprises two thyristors 5, 6 connected in antiparallel, the gate electrodes 11 of which are energized by way of a normally open switch and two resistors 3, 4 connected in series with the load. The switch 9 has a low current carrying capacity and is preferably a reed type switch which, when subjected to a magnetic field, closes thereby rendering the thyristors 5, 6 conductive in alternate half cycles of the supply 1, 2 so controlling the current in the load 10 which may be a contact making device or an electric motor.
