Abstract
548,092. Sparking-preventing in switches. SIEMENS BROS. & CO., Ltd., and BARTLETT, C. J. C. May 23, 1941, No. 6652. [Class 38 (v)] Sparking at the contacts a of automatic telephone relays is prevented by arranging in shunt to the contacts, or to-the load M, a condenser K in series with a resistance R which is adapted to be short-circuited by the contacts of relay M or by contacts mr of a relay MR operated by M and to remain so short-circuited until M has been disengaged sufficiently long for the energy thereof to be absorbed by the condenser. In Fig. 2 (not shown), the contacts mr are replaced by a unidirectional conducting device which allows the load-energy to pass but prevents the condenser-discharge from passing.
