Abstract
A switching circuit (20) comprising first and second switch terminals (2,3) and a switch (21). The switch (21) comprises a first bipolar transistor (22), having a collector connected to the first switch terminal (2) and an emitter connected to the second switch terminal (3), and a second bipolar transistor (23), having an emitter connected to the first switch terminal (2) and a collector connected to the second switch terminal (3). The switch (21) can be turned on by supply of a control current to the base of either the first or the second bipolar transistor.
