摘要： An extinction cover (5) is mounted on a case (4) thereby sealing an extinction chamber (S). This extinction cover has an engaging-force-increased portion (5c1) which strengthens the force of engagement with the case, and an engaging-force-decreased portion (5c2) which weakens the force of engagement with the case. In response to an increase in internal pressure in the extinction chamber due to arc gas generation, the engaging-force-decreased portion establishes disengagement of the case and provides a gap (27) with the case, for linking the extinction chamber to external air, and the engaging-force-increased portion maintains engagement with the case.

摘要： A reversible unit (10) is attached by being mounted over a pair of adjacently disposed electromagnetic contactors (1a) and (1b). The reversible unit (10) includes a pair of interlock plates (11) and (12), a lock piece (13), and a unit case (10b) accommodating the pair of interlock plates (11) and (12) and the lock piece (13). The lock piece (13) rotates in a first direction with the movement of one of the interlock plates (12) in a turn-on operation of one of the electromagnetic contactors (1a) to prevent the movement of the other interlock plate (11), and rotates in a second direction different from the first direction with the movement of the other interlock plate (11) in a turn-on operation of the other electromagnetic contactor (1b) to prevent the movement of one of the interlock plates (12). The unit case (10b) is provided with a lock piece display window (10g) which allows determination of the rotation of the lock piece (13) in the first direction or the second direction.
