The invention relates to the capacitive control of at least one vacuum interrupter chamber (1), which is characterised by a capacitive C-control electrode assembly that can be attached separately to at least one vacuum interrupter chamber (1). The C-control electrode assembly has at least one, preferably concentric, control electrode (2, 3, 14, 15, 16, 17, 18, 24, 25a, 25b, 26, 30, 31a, 31b, 32a, 32b, 33) that is located in an electrically insulating embedding medium (4, 23), said electrode covering, at least partially, a front face region and a cladding region of a vacuum interrupter chamber.
