Abstract
In an embodiment a switching device includes at least one stationary contact and a movable contact movable from a first switching state to a second switching state by a magnetic armature, wherein the magnetic armature has a spring configured to reset the movable contact from the second switching state to the first switching state, and wherein the spring has a first spring region with a first spring constant and a second spring region with a second spring constant which is greater than the first spring constant.
Claims17
A switching device comprising:
- at least one stationary contact;
- and
- a movable contact movable from a first switching state to a second switching state by a magnetic armature,
- wherein the magnetic armature has a spring configured to reset the movable contact from the second switching state to the first switching state,
- wherein the spring has a first spring region with a first spring constant and a second spring region with a second spring constant which is greater than the first spring constant,
- wherein at least a part of the spring is arranged in an opening of a magnetic core of the magnetic armature, and
- wherein the switching device is configured to switch an electrical load.
