Abstract (en)

[origin: DE19547098A1] The cylindrical chamber (2) extends along the central axis (1) and contains a gap (61) with a moving contact in series with the switch-on resistor (65). A resistance contact (33) in parallel with the resistor is closed and opened after the gap. The resistance contact is movable mechanically with the other in a straight line along diametrically opposed parallel axes (7,8). The coupling elements (e.g. 10) in cylindrical aluminium alloy housings on actuating rods (5) contain stacked spring washers which delay their movement during both switch-on and switch-off.
