A rotary knob, particularly an illuminant rotary knob, provides function selection and execution through single-handed operation. The invention includes a light transparent light guide to couple with a compiling controller to facilitate user operations. A plurality of illuminant elements are located around the compiling controller to project light through the light guide to give the rotary knob an illuminant effect.

Rotary knob structure

A keyboard key structure adopted for use on a larger sized key to provide users more effective depressing movements on the key includes two elastic domes to support a key cap in a non-depressed position. The two elastic domes are designed in an unsymmetrical fashion to equip with different compression displacements and flexibility and enable the key cap to move in one direction to reach a depressed position and complete signal input.
