。As shown in FIG. 3, the power transmission switch of a conventional electrically operated switch is directly connected to an electrically operated shaft 1 via a connecting pin 10 to a worm gear 2 which also serves as a manually operated shaft. When performing manual operation, a limit switch 5 provided on the handle insertion shaft for manual edge operation is opened by inserting the handle 7, and the structure is such that power operation cannot be performed electrically.

能な構造となっている。An embodiment of the present invention will be described below with reference to FIG. In this embodiment, the electrically operated switch is operated both manually and mechanically, and is composed of an electrically operated shaft 1, a worm gear 2 that also serves as a manual operating shaft, and a collar 3 that connects these. . Normally, electric operation is connected to the electric operation shaft by the limit switch 5 provided on the manual operation handle insertion shaft being in the closed state and by the spring 4 inserted between the worm gear 2 and the connecting collar 3. In addition, the worm gear 2 and the connecting collar 3 are connected to a key 8 which is provided in advance.
It is fixed in one rotational direction by a keyway 9 and has a structure that allows electric operation.
次に、手動操作を実施した状態の構造を第２図に示す。Next, FIG. 2 shows the structure under manual operation.
