Abstract (en)
A switch device (P) for electrical relays (R), comprising at least one static electronic component (K), which is commanded to run, causing a short-circuit between the electrical contacts of the relay (R), during the brief time period during which the switching of the relay (R) takes place; this allows the contacts (R1, R2) of the relay (R) to be opened and/or closed practically without a drop in the voltage and current flowing between them, thus avoiding the occurrence of electrical arcs and substantially extending the electrical life of the relay (R).
