Abstract (en)
An electrical vacuum switch includes a coil (68) made in the metallic base (42) of the bulb (38). The metallic base (42) constitutes a contact current intake, this intake having a radial conducting path and a path forming a turn (68), which are electrically connected in parallel. So as to promote the flow of the current in the turn, which constitutes an axial magnetic blow-out coil, the base (42) has corrugations (74) or a slot (76) which lengthen the radial conducting path. <IMAGE>
