    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.

    摘要： An electromagnetic contact device has a contactor holder (40), which moves a mounted movable contactor (42a) according to a displacement of a movable core (32) forming an electromagnet (30) for operation. The contactor holder (40) is being housed together with the electromagnet (30) for operation in a case (1). The case (1) has a lower case portion (10) housing the electromagnet (30) for operation and an upper case portion (20) engaging with the lower case portion (10) while being stacked on the lower case portion and houses the contactor holder (40) advanced from above. The upper case portion (20) has a recess (21) with an upward opening and houses the contactor holder (40) placed on the bottom wall of the recess (21). The lower case portion (10) houses one selected either a DC-only electromagnet (30b) or an AC-only electromagnet (30a).

    摘要： The electromagnetic contactor enables a reliable return to a pole open position without increasing the spring force of a return spring. In an electromagnetic contactor, an electromagnetic device having an exciting coil and a contact mechanism having a return spring are disposed in parallel, and the electromagnetic device and contact mechanism are linked by a drive lever. The electromagnetic device has a polarized electromagnet having a magnetic circuit that includes a permanent magnet generating a suction force that moves the contact mechanism to a pole open position side when the exciting coil is not energized. The drive lever is fixed to either one of the electromagnetic device or contact mechanism and contacts with the other with no gap at least when the contact mechanism is moved to the pole open position side. The return force of the contact mechanism is covered by the suction force of the permanent magnet.
