PURPOSE:To improve the operability of a controller by setting the 1st knob having a flange for revolution to the shaft of a controller containing a switch and also providing the 2nd knob which interlocks the 1st knob and moves in the axial direction. CONSTITUTION:A rotary operation knob 7 is fixed to a shaft 6 of a volume 5 containing a switch, and a knurled part 8 is formed at the outer circumference of the shaft 6. At the same time, a discoid flange 9 is formed in a body with the shaft 6. A knob operation part 11 is formed at the upper part of a slide knob 10, and an indication groove 12 is formed at a part of the part 11. Furthermore a U-shaped engaging bar 13 is extended integrally from the knob 10 and holds the flange 9. A power switch is applied by sliding the knob 10 toward an arrow A to give tension to the shaft 6 with the bar 13. When the knob 7 is turned toward an arrow C and D, the shaft 6 is revolved to vary the volume 5. Thus it is possible to operate the switch with no variation of the volume 5. |
