Description

  The present invention relates to a rotary switch including a switch knob that is pressed and a shaft portion that serves as a rotation fulcrum of the switch knob.

  Conventionally, various switches are provided on various operation panels and the like for the operation.

  As such a switch, a rotary switch including a switch knob that is pressed and a shaft portion that serves as a rotation fulcrum of the switch knob is also well known.

  On the other hand, the operation panel having such a rotary switch is provided with the surface of the switch knob tilted for the purpose of improving the operability associated with the overall design viewpoint and the installation space limitation. Also known is a rotary switch (see, for example, Patent Document 1).

  The rotary switch disclosed in Patent Document 1 is tilted so that the operation surface which is the surface of the switch knob is lowered toward the front, and the rotary shaft having an axis line in a direction perpendicular to the tilt direction is switched. It is integrally provided on the base side of the knob.

  On the other hand, for example, there are some which are arranged on a center console whose entire surface is curved in the vehicle width direction as seen in recent vehicle heater control units, audio equipment control units, and the like.

  In some cases, a rotary switch is also used in an operation switch or the like disposed on a control unit provided on such a curved surface.

  At this time, as described above, when the center console is curved in the vehicle width direction, from the viewpoint of operability and functionality of the rotation switch, the rotation direction is the vertical direction, that is, the tilt direction of the switch knob. It is also conceivable to use a rotation switch that extends, that is, rotates in the vertical direction.
