PROBLEM TO BE SOLVED: To provide an operating device for a by-pass switch whose entire mechanism is reduced in size.SOLUTION: A handle shaft side lever 210 and a main contact shaft side lever 220 are provided. The main contact side lever 220 which is connected to a movable contact is rotatable around a main contact axis 221 as a central axis. A pin 222 is firmly fixed to the main contact side lever 220. The handle shaft side lever 210 is rotatable around a handle shaft 211 as a central axis and is formed into a bent shape so as to abut against the pin 222 of the main contact shaft side lever 220 in a vicinity of the bottom. When forced tripping from the by-pass side to the adjustment device side is carried out, the pin 222 of the main contact shaft side lever 220 is pushed out by a flat part 213 of the handle shaft side lever 210. In this case, the main contact shaft side lever 220 turns, whereby a link arm 230 linked to the main contact shaft side lever 220 and an operating lever 240 turn, and a contact operation is finished to complete the forced tripping. |
