Electrical switch e.g. power switch, for protecting electric or electronic circuit from high direct voltage, has insulating elements inserted in intermediate chamber between contacts to remove lighting arc that is formed between contacts

摘要

The switch (10) has a pole including two separable contacts (16A, 16B). Adjustable planar insulating elements (20) are inserted in an intermediate chamber (26) between the separable contacts to remove a lighting arc that is formed between the contacts. The intermediate chamber is formed during the separation of the contacts that are arranged within a switching chamber (14). The insulating elements are configured in such a manner that the insulating elements divide the switching chamber in a closing position into two regions that are separated from each other.
