Abstract: A vacuum interrupter including a vacuum bottle, a fixed contact extending through one end of the vacuum bottle and a movable contact positioned within the vacuum bottle relative to the fixed contact so that a gap is defined between the fixed contact and the movable contact when the vacuum interrupter is open and the fixed contact and the movable contact are in contact with each other when the vacuum interrupter is closed. An insulated drive rod is rigidly coupled to the movable contact opposite to the fixed contact and a circular flexible conductor is coupled to the movable contact and flexes when the movable contact is moved by the drive rod. The flexible conductor can be, for example, a laminate structure including a plurality of stacked conductive laminates each having a plurality of spirals separated by gaps or a linear spring trampoline conductor.

Abstract: A method for separating welded contacts in a magnetically actuated switch assembly that includes providing multiple actuator hammer blows to the contacts. The method includes causing the contacts to close using, for example, a manual actuation device and detecting a high current condition that occurs when the contacts are closed. The method further includes electrically actuating the actuator to open the contacts in response to detecting the high current condition and determining that the contacts have not opened in response to the actuator being actuated because they are welded together. The method also includes electrically actuating the actuator to close the contacts when it is determined that they are welded together and again electrically actuating the actuator to open the contacts.
