Bistable change-over contact BK-390 for bypass-tubes

The BK-390 is a magnetically-operated changeover switch that permanently changes its electric switching status due to a switching magnet passing by (float/weight) depending on the direction of movement. The switching status is shown in the status window of the housing cover. Application: for mounting on the side of bypass tubes. The number and position of the changeover contacts can be chosen at random.
