Abstract

1479577 Transformers DAVID GRIFFIN Ltd 30 April 1976 17633/76 Heading HIT [Also in Division H2] A transformer 15 used for supplying an electric blanket from an A.C. supply is associated with a normally closed thermally operated switch 13 the switch being operated when the transformer temperature reaches a threshold value. The switch 13 may be mounted so as to be responsive to the temperature of the secondary winding 14 of the transformer 15-as shown in Fig. 3-or alternatively, to respond to the temperature of the core 25.
