Abstract
In a multi-operational electronic device of the present invention, a first switch, which operates when an operating lever is tilted, is so configured that a circular domelike resilient movable contact large enough to cover a plurality of first fixed contacts is partially turned inside out. A connecting part connects an outer cylinder holding a rotary resilient contact, which effects generation of a rotary signal, with an inner cylinder fixed to an operating shaft so that the outer and inner cylinders move with each other in a rotating direction to generate the electric signal and contract vertically to press a central switch.
