Abstract
The process for controlling an electromagnetic relay comprises at least one contact, controlled by a voltage or current supply. In accordance with the invention the control is modulated according to the voltage or current supply, to the contacting voltage required to close the contact of the relay, and to the maintaining voltage which is sufficient to maintain this closure.
