Abstract
A current switch is disclosed. The current switch comprises an arrangement for converting the difference between input signals fed to first and second input terminals into the difference between output signals from first and second output terminals; a power source for supplying a constant current to the converting arrangement; constant voltage means connected between a first output terminal of the converting arrangement and the power source; a first resistor, one end of which is connected to the power source; a second resistor, one end of which is connected to the other end of the first resistor and the other end of which is connected to the first output terminal of the converting arrangement; and a third resistor, one end of which is connected to the other end of the first resistor and the other end of which is connected to the second output terminal of the converting arrangement, wherein an output signal is taken out of the second output terminal.
