<p>The present invention describes a high-voltage electric switching arrangement (10) in a metal casing (300), which includes: a first switch (20) controlling, under a first switching mode, the establishment of electric contact between the first connector (30) and a third connector (50) which is earthed; the second connector (40) and the third connector (50) are separate from one another and spaced apart from the switch (20); the first switch (20) includes a first means (80, 100, 150, 200) for pushing a contact element (120) enabling the first mode by moving said contact element (120) between the first and third connectors (30, 50). The switching arrangement is finally characterised in that the second connector (40) includes a second switch (21) including a second means (71, 91, 151, 201) for moving a contact element (111) enabling, under a second switching mode, the establishment of electric contact between the first connector (30) and a second connector (40) and enabling, under a third switching mode, electric insulation of the three connectors (30, 40, 50) by moving said contact element (111) between the second connector (40) and an electric contact point (P) of the first switch (20).</p> |
