Gas shut-off switch

A gas shut-off switch (1) provided with various operating positions and intended to be isolated in a dielectric gas inside an electrical switchgear cell (19) comprising at least one housing (2), said housing (2) being structured in two parts, which in turn comprises:

• a first part that includes a first arc chamber (6) and a second part that includes a second arc chamber (7), where the first arc chamber (6) incorporates a first fixed contact (3) and the second arc chamber (7) incorporates a second fixed contact (4);
• a movable contact (5) having a rotary motion to electrically connect with said fixed contacts (3, 4);
• and
• at least one electric arc blowing means (8);
• characterized in that:
• an electrical contact and separation between the movable contact (5) and each of the fixed contacts (3, 4) occurs in different arc chambers;
• the blowing means (8) is jointly connected to the movable contact (5) to perform a same movement path as the movable contact (5) in the gas shut-off switch (1) opening and closing;
• and in that
• each of the first arc chamber (6) and the second arc chamber (7) comprises at least one communication path (9, 10) with an exterior of the housing (2) that allows both an exit of gases generated in an electric arc blowing and entry of clean dielectric gas in the first arc chamber (6) and the second arc chamber (7).
