Abstract

A two-column electrical disconnector (10), comprising a female arm (11) and a male arm (12), provided with a contact head (13) that is adapted to enter a contact seat (14) of the female arm (11). The contact head (13) has contact recesses (15) with a substantially V-shaped profile which are open in order to receive, upon closure of the disconnector (10), contact pads (16) of the female arm (11), with contact of the type on two points (A, B). The female arm (11) comprises two half-arms (17a, 17b) that are arranged side by side so as to form between them, at a free end thereof, the contact seat (14), having thereat the contact pads (16), elastic means (18) for contrasting the divarication of the half-arms (17a, 17b) being provided, said half-arms (17a, 17b) partially divaricating, in contrast with the elastic means (18), when the contact pads (16) engage the contact recesses (15) upon closure of the disconnector (10).
