Abstract
In an electronic circuit of a current switch construction in which the emitters of a first transistor and a second transistor are commonly connected to a constant-current supply, and a load resistor is connected to the collector of the first transistor, thereby to take out an output from the collector, the improvement being a pnp-type transistor, in which temporarily flows an electric current to a collector circuit of the first transistor when it is rendered non-conductive, which is inserted in a collector circuit of the second transistor.
