Abstract: AN ELECTRIC SWITCH HAVING A COMPARTMENTALIZED METAL CASE FOR RECEVING DISCONNECTORS The metal-clad electric switch having gas insulation and a metalo case (1) comprises a case whose inside volume is subdivided into at least two compartments (1B, !C) separated by a leakproof partition (3). A first disconnetor (4) is disposed in one of said compratments and comprises a first blade (4A) co-operating with a first connection terminal (4B). A second disconnector is disposed in the other compartment and comprises a second blade (5A) co-opreating with a second connection terminalo (5B). The blades are secured to a common rotary shaft (7) passing in leakproof manner through said partition and providing electrical conduction betweeni said blades.
