Abstract
The object of the present invention is to provide an operation unit for switches for improving the stop position precision of motor operation, improving the stop position precision (permitted range of handle pull-out ) by manual operation, and improving the stop position precision of the motor operation and the stop position precision (permitted range of handle pull-out) by the manual operation. The rotation of a grooved camshaft 5 for forming a groove 10 engaged with a roller 13 on the surface of a cylinder drives the roller 13 for rotating an output shaft 11, and axial displacement to the rotation of the grooved camshaft 5 is eliminated near a stop position, thus preventing the output shaft 11 from being rotated even if the grooved camshaft 5 is rotated.
