PROBLEM TO BE SOLVED: To prevent a front door body of a switch box body from mechanically shutting unless many switches are turned on or off simulteneously. SOLUTION: A switch lever position detecting plate 8 positioned on a front of a switch lever 7 is attached with a switch box 1 slidably in right and left directions, and unless all of a switch levers 7 are turned on or off, the switch lever position detecting plate 8 does not slide, and thereby, a lock piece 4 on a front door body 3 is engaged with neither of a pair of lock holes 13, 14 disposed on the switch lever position detecting plate 8. Therefore, the front door body 3 is not locked with the switch box body 1. |
