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