Description

Rotary switch {ROTARY SWITCH}

The present invention relates to a switch technology, and more particularly, to a rotary switch having an O-ring gasket mounted on an insulating housing around a rotary operation lever and improving a touch sensation and sufficiently performing a waterproof function.

With the development of science and technology, many electronic and electric products are continuously created, serving people, and providing convenience for everyday life and work. In recent years, the rapid development of the Internet has used portable electronic products such as notebook computers, tablet computers, smart phones, digital terminals, and digital cameras anywhere, anytime. Today, there is a tendency to produce mobile electronic products that are lightweight, thin, short and small in character. As a result, all relevant components for mobile electronics must meet these electronic product design concepts.

The design of switches for use in mobile electronics varies widely. The push-button switch is constituted by a spring-type button for touching the induction terminal, and is electrically contacted to generate an electric signal. However, the push-button switch can only perform a simple on / off operation and can not be rotated to perform the adjustment operation. There is a known multi-directional switch comprising an electrically insulated bottom cell member, a plurality of inductive terminals mounted in respective terminal grooves of the electrically insulated bottom cell member, a plurality of shroud flanges mounted on the electrically insulating bottom cell member, a control disk supported on the shroud and having a plurality of fingers spaced apart at equal intervals on the upper surface thereof and a plurality of electrical contacts located on the opposite bottom surface, And an electric insulating cover for partially exposing the disk to the outside. In operation, the user can depress one finger groove of the control disk and press each of the shuffles to bring each electrical contact of the control disk into contact with its respective inductive terminal, thereby generating a corresponding electrical signal. The design of such a multi-directional switch is still insufficient in function. When pressing one finger groove on the control disk, the pressurized force may not be accurately given in the selected finger groove, and the corresponding sherfennel may be deflected and permanently damaged. At this time, the shrapnel is forced into the deep inside of the bottom cell member and does not return to its original shape, thereby resulting in contact instability and failure. Improvement is required.
