  • the rotary knob 310 has a knob body 311 and a knob cover portion 315, the knob cover portion 315 being outside the end of the knob body 311 of the rotary knob 310. It extends toward the cover to take the structure surrounding the rotary switch 330. That is, when the rotary knob 310 and the rotary switch 330 in the normal state are projected on a plane perpendicular to the substrate extension 210, in other words, on the xy plane (see FIG. 1), the rotary switch 330 The projection area B (refer to FIG.
  • the projection area indicated by reference numeral B denotes the projection area by the rotary switch 330
  • the transparent areas indicated by reference numerals A1 and A3 denote the projection area by the knob body 311, and reference numeral A2.
  • the transparent area to be represented represents the projection area by the knob cover portion 315.
  • the knob body cover portion 315 includes a knob cover inclined portion 316 which is inclined with respect to the x-axis and the z-axis when the rotary knob 310 is disposed in a normal state.
  • the inclination angle of may be appropriately selected depending on the movable range of the rotary knob. For example, in FIGS.
  • the rotational state of the rotary knob according to the present invention to the maximum both sides is shown step by step.
  • the angle of the knob cover inclined portion 316 is excessively small or excessively large, the knob cover is shown. Since the liquid foreign matter through the inclined portion 316 may not be smoothly guided downward, proper angle selection is necessary.
  • the housing may further include a component for achieving discharge of the liquid foreign matter introduced through the cover through hole 113. That is, the cover drain hole 117 is disposed in the housing cover 110, and the cover drain hole 117 is formed to communicate with the outside at a corresponding position of the body drain slope 126.
  • the liquid foreign matter flowing through the cover through hole 113 is guided to flow downward quickly through the knob body 311 and / or the knob cover portion 315 of the rotary knob 310 and the body drain slope.
  • the liquid may be kept clean by preventing liquid foreign matter from damaging the rotary switch 330 and preventing it from flowing into the interior of the housing body 120 by allowing the liquid to quickly flow out through the cover 126 and the cover drain 117. have.
  • the rotary detent part provided in the rotary switch unit according to the present invention may be implemented in a ball / spring type.
  • the rotary switch unit according to the present invention can be applied to a variety of applications, such as may be applied to a switch used in a vehicle, such as a head lamp level control device.
