A switch for high-voltage overhead conductors comprises fixed (1) and movable (2) insulators with a main contact having fork (4) and blade (3) and a secondary contact with a release spring (5) and hook (6). An upper stop (8) reduces the end position of the release spring leg (5') to a separation (L) not less than that (l) of the lower stop (7). |
