Abstract
PURPOSE: To improve the operation balance of a moving contactor, by providing a spring which normally applies an elastic force to the moving contactor in a direction to close it but can turn the contactor in a direction to open it.
CONSTITUTION: The spring 5 which normally applies an elastic force to the moving contactor in a direction to close it but can turn the contactor in a direction to open it, and a coiled spring 19 which applies an elastic force to a button 7 which comes into contact with the moving contactor to indicate the operation in connection with the opening of the contactor are provided. The elastic forces of the springs 5, 19 are applied to the moving contactor in the opposite direction. The elastic force of the spring 5 is made stronger than that of the coiled spring 19. Thereby, the operation balance of the moving contactor is improved and the contactor can be driven by a low force. This makes it possible to operate the contactor stably and smoothly.
