Abstract

The contact breaker has a rotary control device and a contact arrangement in a gast-tight housing, being actuated by a magnetic system, preferably in the form of a sealed reed switch. In order to increase the switching precision for an arbitrary number of switching operation, the magnetic plug is controlled in such manner that the OFF threshold takes place in a region of great flux change in time. The sealed reed switch (16) is operated by an asymmetric magnetic alternating field, which exceeds the switch ON threshold in one direction of the magnetic flux only, while the OFF threshold remains in the region of greater time change range. The contact breaker may use a permanent magnetic system.
