Abstract

The present invention relates to improvements in circuits for electronic telegraph relays consisting of two transistors connected in series of the opposite conductivity type whose bases are fed with the control signal, while the output signal with respect to the grounded center the supply potential is taken from the junction point of two equal electrodes of the transistors and the supply potential is applied to the other electrodes of the transistors.
