is integrally molded from synthetic resin, and the push switch 4 is operated by bending the hinge portion 10b and rotating the operating portion 10a and the operating piece 10d. Therefore, the hinge portion 10b of the operating button 10 is easily damaged due to fatigue, and the mechanical strength of the hinge portion is weak, making it impossible to take a large operating stroke of the operating portion 10a and the actuating piece 10d. Since the pivot point of the hinge portion 10b is unclear, there is a drawback that the operation feeling is poor.

In view of the above circumstances, this idea has an extremely simple structure, has high mechanical strength of the hinge, allows for a large operating stroke, makes the rotational fulcrum of the hinge clear, and provides a good operating feeling. The present invention provides an operating device for electrical components in electrical equipment, in which a hinge member of an operating button is constructed of a leaf spring.

By the way, in this device, since a leaf spring is used as the hinge member of the operation button, the mechanical strength of this member is extremely high. Therefore, the operating stroke of the operating button can be increased. Further, since the rotational fulcrum of the operation button 33 is specified at the bent portion between the mounting portion 35a and the fixed portion 35b of the leaf spring 35, a good operation feeling of the operation button can be obtained.

Further, in this embodiment, by changing the width of the hinge portions 35c, 35c of the leaf spring 35, the force for operating the operation button 33 can be easily adjusted.

As explained above, according to this invention, one piece of a plate spring formed with an L-shaped cross section is fixed to a fixed member, and an operation button consisting of an operation part and an actuation piece is connected to the other piece of the plate spring. The rotation fulcrum of the hinge structure between the fixed member and the operation button is formed only by the L-shaped bent portion of the leaf spring, and the actuator of the electric component is arranged opposite to the actuation piece of the operation button. Because of the arrangement, the mechanical strength of the movable parts is high, so the movement stroke of the operation button can be made large, and the rotational fulcrum of the operation button is clear, so the operation feeling of the operation button is improved. Effects such as good results can be obtained.
