Abstract (en)

[origin: EP4105958A1] The traveling contact connected to and separated from the fixed contact, the rod-shaped latch (11) that is rotatably pivotally supported in the barycentric region between one end having a latch engaging part (11a) and the other end driven by tripping, the insulating rod (6) having a latch pin (S1) at one end that engages with the latch engaging part, the input actuator (7) that drives the other end of the insulating rod, and the spring (9) for opening that drives the traveling contact in the opening direction are provided, when the other end of the latch is pulled off and driven while the traveling contact is closed to the fixed contact, the engagement between the latch engaging part and the latch pin is disengaged, and the traveling contact is driven in the opening direction by the opening spring, with the traveling contacts open, the latch pin is driven in the input direction via the insulating rod by the input actuator, the latch is driven in the input direction via the latch engaging part, and the traveling contact is driven in the opening direction with the fixed contact, it is not easily affected by vibration, and it is possible to stabilize the closing operation and the closing holding.
