    摘要: A plurality of terminal chambers (20a) to (20e) is formed in a housing (16) by using a plurality of partition walls (24a) to (24e) to partition. In the terminal chambers, fixed contactors (31) each having a fixed contact point (31d) and a terminal screw (31a) are mounted. Engaged portions (31b) are formed integrally with the fixed contactors. Further, a press-fit engaging portion (26) is provided in each of the terminal chambers. The terminal chamber is formed as a space different from a space accommodating a movable contact point support, and the press-fit engaging portion is engaged by the engaged portion by press-fitting.

    摘要: A reversible unit (20) has a pair of interlock plates (21, 22) detachably connected to operation indication pieces (4a, 4b) of a pair of electromagnetic contactors (1a, 1b) and moving in the same direction as the moving direction of the operation indication pieces, a lock piece (23) connecting with the pair of interlock plates (21, 22), a first normally-closed contact (24), and a second normally-closed contact (25). In a closing operation of one of the electromagnetic contactors (1a), the lock piece (23) moves one of the interlock plates (21) and prohibits the movement of the other interlock plate (22). The first normally-closed contact (24) is connected in series in a power supply circuit to an exciting coil (6b) of the other electromagnetic contactor (1b). One of the interlock plates (21) has a first opening operation engagement portion (34) releasing the first normally-closed contact (24) when the interlock plate (21) moves.

    摘要: A movable hook portion (13) provided in a unit side coupling surface (2a) of an accessory unit (2) includes a hook portion main body (14), which is formed with a movable claw (23a) and a pressed piece (22), and a straight spring (15), slidably accommodates the hook portion main body (14) in a main body accommodation concave portion (16) formed in the unit side coupling surface (2a), and accommodates the straight spring (15) in a spring accommodation concave portion (17a) formed in the unit side coupling surface (2a) so as to be orthogonal to a sliding direction of the hook portion main body (14), with a middle portion in a length direction of the spring being engaged with the hook portion main body (14). When the hook portion main body (14) is slid in a disengaging direction which brings the movable claw (23a) and a hooking hole (8a) of an electromagnetic contactor (1) into a disengaged state by pressing the pressed piece (24), an elastic restoring force of the straight spring (15) elastically deformed into a bow-like shape acts on the hook portion main body (14) in a direction opposite to the disengaging direction.
