Patent number: 11710606Abstract: A system includes a mechanical switching device having a first moveable contact operatively connected to selectively contact a first static contact. A second moveable contact is operatively connected to selectively contact a second static contact that is electrically connected in parallel with the first static contact. The first and second moveable contacts are mechanically connected to each other to move between a closed circuit position and an open circuit position. The first moveable contact contacts the first static contact before the second moveable contact contacts the second static contact as the first and second moveable contacts move into the closed circuit position from the open circuit position. The first moveable contact disconnects from the first static contact after the second moveable contact disconnects from the second static contact as the first and second moveable contacts move from the closed circuit position into the open circuit position.Type: GrantFiled: August 11, 2021Date of Patent: July 25, 2023Assignee: Hamilton Sundstrand CorporationInventors: Francis C.
