Document Type and Number:
WIPO Patent Application WO/2021/090599
Kind Code:
A1
Abstract:
At least a portion of a movable switch (20) is mounted on a detection surface (11) that can detect a capacitance change accompanying the approach or contact of a finger (F) of a user. A knob (21) can be displaced with regard to the detection surface (11) in accordance with an operation by the finger (F) of the user. A first conductive section (221) is positioned in an area of the knob (21) that is distant from the detection surface (11). A plurality of second conductive sections (222) are positioned in areas of the knob (21) that are closer to the detection surface (11) than the first conductive section (221). A conductive path (223) electrically connects the first conductive section (221) and the plurality of second conductive sections (222).
