<p>Isolator switch of the type comprising a blade linked, at a first end, to a first connector and to means allowing, during an opening phase, a first rotation about itself and a second rotation about an axis, the said blade carrying, at its second end, a contact hammer interacting with a jaw linked to a second connector, the isolator switch comprising means (10A, 13, 14, 20, 21, 29) so that, during an opening operation, after the blade (1) has carried out its rotation on itself causing the electrical disconnection of the hammer (10) and of the jaw (9), the current is first of all tapped off, then switched through a switch (20), the latter opening under the control of a rapid-breaking mechanism (29) controlled by the movement of the blade, characterised in that the said means comprise two horns (13, 14) between which a sacrificial hammer (10A) moves with friction. <IMAGE></p> |
