Overvoltage protective device for e.g. electronic measuring circuit, in electrical system, has inner electrode held in electrically conductive contact with electrode in position against restoring force of spring element

摘要

The device has a housing (2) with a chamber (8) connected to an electrode (6), and another electrode (9) spaced at a distance from the electrode (6), and an inner electrode (10) arranged in the chamber. A connector (3) is connected with a third electrode (5) and another connector (4) is connected with the electrode (9) in an electrically conductive manner. The electrode (10) is held in electrically conductive contact with the electrode (6) in a position against a restoring force of a spring element (11). The inner electrode is arranged at a distance from the electrode (6) in another position.
