Abstract:
1. A rotary switch comprising: a body having a fixing surface; a thin-plate-like flexible substrate fixed onto the fixing surface and having a plurality of first electrodes arranged along a first circle on the surface, as a first electrode placement surface, that is opposite the surface in contact with the fixing surface; a thin-plate-like electrode plate having a plurality of second electrodes arranged along a second circle on a second electrode placement surface facing the first electrode placement surface, the electrode plate being rotatable in the second circle; a dial having an operating surface and rotatable along the second circle; and a resilient member interposed between the surface, as an opposite operating surface, that is opposite the operating surface of the dial and the surface, as a resilient member surface, that is opposite the second electrode placement surface of the electrode plate, wherein the electrode plate has a plurality of electrode plate protrusions in the circumferential direction on the resilient member surface, the dial has a plurality of dial protrusions in the circumferential direction on the opposite operating surface, and each of the electrode plate protrusions is positioned between the corresponding pair of the dial protrusions or each of the dial protrusions is positioned between the corresponding pair of the electrode plate protrusions.
