ABSTRACT VACUUM ELECTRICAL SWITCH A vacuum electrical switch comprises a coil (68) arranged in the metal base plate (42) of the cartridge (38). The metal base plate (42) constitutes a current input to the contact, this input having a radial conducting path and a path forming a spiral (68), electrically connected in parallel. In order to enhance the current flow in the spiral, which forms an axial magnetic blowout coil, the base plate (42) has ripples (74) or a slit (76) which lengthen the radial conducting path. Refer to figure 2.
