Document Type and Number:
Japanese Patent JP5504925
Kind Code:
B2
Abstract:
A reversible unit (20) is provided with a pair of interlock plates (21, 22) which are detachably connected to operation indication pieces (4a, 4b) of a pair of electromagnetic contactors (1a, 1b) and which can move in the same direction as the movement direction of the operation indication pieces, a lock piece (23) which connects 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) allows one of the interlock plates (21) to move, 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 of the electromagnetic contactors (1b), and one of the interlock plates (21) is provided with a first opening operation engagement portion (34) which opens the first normally-closed contact (24) when the interlock plate (21) moves.
