Abstract

616,144. Sparking-preventing in switches. SCHWAB, H. Aug. 29, 1946, No. 25925. Convention date, May 3, 1941. [Class 38 (v)] The contacts of a voltage regulator or, as shown, a double - current telegraphic transmitter, are shunted by a condenser C and one or more rectifiers R in series. The rectifier is so connected that when the contacts are opened a low-resistpath is provided for the current, whilst when they are closed the condenser discharges through a high-resistance path.
