Abstract
To reduce the rebound of the main armature with contact carrier in response to the switching operation of a contactor, magnetic-chamber base of contactor housing is provided with two support areas for the magnet yoke, said areas having different resiliencies. To this end, the magnetic-chamber base, designed so as to be capable of vibrating, has a supporting strip whose ends act as magnet-supporting areas.
Claims9
A switchgear housing for an electromagnetic switching device including a magnet yoke and a magnet armature, comprising:
- a magnetic chamber including a vibratable magnetic-chamber base, the magnetic-chamber base having a surface including a supporting strip, the surface facing an interior space of the switchgear housing, the supporting strip including a first end configured as a first magnet-supporting area and a second end configured as a second magnet-supporting area, the first magnet-supporting area having a first elastic resiliency and the second magnet-supporting area having a second elastic resiliency, the first elastic resiliency being different from the second elastic resiliency, the first magnet-supporting area being retained at the first end only by the magnetic-chamber base;
- wherein the first magnet-supporting area and the second magnet-supporting area support the magnet yoke, and the magnet armature is positionable in the magnetic chamber.
