Abstract (en)
[origin: EP2546847A1] A medium or high voltage switch has a switching assembly (12) actuated by at least one drive (18, 19). The drive (18, 19) comprises a plunger (27) arranged between two Thomson coils (37, 38). The plunger (27) is located in a chamber (26), with vents extending through the wall (25) of the chamber (26) for controlling and in particular for damping the motion of the plunger (27).
