摘要

Improvements in the electronic multiple triggers of relays, characterized in that they consist of a series of control units formed by vacuum valves, when one of them acts, the others are blocked until the normal operating regime is restored by a putting circuit. In progress, these valves being provided with their cathode circuit in common, through the trip relay, which acts when one of the valves becomes conductive, automatically and negatively polarizing the bars of the other valves.
