ELECTRICAL SWITCHING DEVICE WITH A TRIPLE MOTION CONTACT ARRANGEMENT |
| 摘要 |
A contact arrangement has a longitudinal axis (z) with a first contact group having a first contact and a second contact, and a second contact group having a third contact and a fourth contact. The first contact interacts electrically and mechanically with the third contact, and/or the second contact interacts electrically and mechanically with the fourth contact. At least one mechanical coupling is provided for transmitting an actuation force to the second contact group and thereby moving the second contact group. The third and the fourth contact can move in such a way that their speeds differ along at least a portion of a travel path of the third contact or of the fourth contact. |

1. Contact arrangement having a longitudinal axis (z), and comprising:
a first contact group with a first contact and a second contact; and a second contact group with a third contact and a fourth contact; wherein the first contact interacts electrically and mechanically with the third contact, and/or the second contact interacts electrically and mechanically with the fourth contact, for closing and opening the contact arrangement; wherein at least one mechanical coupling is provided for transmitting an actuation force to the second contact group for moving the second contact group; and wherein the at least one mechanical coupling is adapted to move the third contact and the fourth contact in such a way that their speeds will differ along at least a portion of a travel path of the third contact or along at least a portion of a travel path of the fourth contact. |
