[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch operating device used for a pole switch for electric power or the like.

[0002]

2. Description of the Related Art In a conventional switch operating device, when it is automatically operated, it is held by a spring force and a mechanical latch mechanism at the time of making and breaking, and a solenoid coil is excited by a command of making and breaking. The latch mechanism is released, and the spring release force closes and shuts off.

In the case of manual operation, the latch mechanism is released by another latch release mechanism, and the manual operation is performed by the handle.

[0004]

In the case of the above-mentioned conventional device, during automatic operation, the stored force of the spring is held by the latch mechanism, and the latch mechanism is released by the excitation of the solenoid coil to turn on / off the switch. Therefore, a latch mechanism and a solenoid coil are required, and there is a problem that the structure becomes complicated.

Further, in the case of manual operation, there is a problem that a latch release mechanism for bringing the latch mechanism into a released state is required separately.

The present invention has the above points in mind, simplifies the structure by eliminating the need for a latch mechanism and solenoid, and
It is an object of the present invention to provide an operating device for a switch which does not require a latch release mechanism and can be easily operated manually.
