Title:
MULTI-CIRCUIT SWITCH
Document Type and Number:
Japanese Patent JP3683743
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a multi-circuit switch capable of disabling the other maintenance switch contacts from being closed when one maintenance switch contact is closed among a plurality of maintenance switch contacts.
SOLUTION: In this multi-circuit switch, when one maintenance switch contact is closed, interlock mechanisms 41a to 41e disable all the other maintenance switch contacts not to be closed from being closed by moving a maintenance lock member 47 common to all the maintenance switch contacts from a non-lock position C to a lock position D. Maintenance mechanism operating shafts 42 for closing/opening the respective maintenance switch contacts are each formed so as to allow a maintenance mechanism operating handle to be mounted thereon, Only when one maintenance mechanism operating handle 91 is mounted on a corresponding maintenance mechanism operating shaft 42, the maintenance mechanism operating handle is linked to the lock link 47, which is interlockingly moved from the non-lock position C to the lock position D by the closing operation of the maintenance mechanism operating handle.
