Claims

[Scope of utility model registration request]

a frame, an insulating substrate integrated with the frame and having a pattern formed on its surface, a knob rotatably supported on the frame for see-saw operation, and a knob rotatably supported between the frame and the insulating substrate. a slider holder having a gear on its periphery and fixed to one side a slider that slides on the pattern on the insulating substrate; a connecting portion; and an operating portion formed at both ends of the connecting portion; has a rack that meshes with the gear of the slider receiver, and the operation part has a tapered surface on which a knob protruding from the inner bottom surface of the knob can come into contact, and a spring engagement that extends from both operation parts in directions opposite to each other. It has a driving body with a protrusion for stopping, and a pair of elastic arms by bending both ends of the bottom.
A seesaw characterized in that the bases of both arms are engaged with protrusions that hang down from the frame, and the ends are U-shaped leaf springs that are stretched between the protrusions of the operating section of the drive body. Operated electrical parts.
