Zusammenfassung:PROBLEM TO BE SOLVED: To make a knob unlikely to separate from a rotor and, to perform a rotating operation of the rotor even in a state where the knob is detached, in a rotary switch comprising the knob that is freely mounted to the rotor.SOLUTION: A rotary switch comprises: a circumferential groove 31 with which a rotor 3 is formed on the end face thereof; and a tool groove 32 into which a tool can be inserted when detaching a knob 1, in a central part 391 inside of the circumferential groove 31. The knob 1 includes a projection 12 corresponding to the circumferential groove 31. An inner recess 14 inside of the projection 12 and the central part 391 are fitted and an outer recess 11 outside of the projection 12 and a marginal part 392 outside of the circumferential groove 31 are fitted, such that the knob is mounted. In the case of detachment, the rotor 3 can be rotated by a rotating operation of the tool that is inserted into the tool groove 32.SELECTED DRAWING: Figure 1 【課題】ロータに装着自在なツマミを具備するロータリースイッチにおいて、ロータからツマミを外れ難くするとともに、たとえツマミが脱着した状態でもロータを回転操作できるようにする。【解決手段】ロータ3が端面に形成された周溝31と、周溝31より内側の中心部391にツマミ1の脱着時に工具の差し込みが可能な工具溝32とを有する。ツマミ1が、周溝31に対応する突条12を有し、突条12より内側の内凹部14と中心部391とを嵌合させ且つ突条12より外側の外凹部11と周溝31より外側の縁部392とを嵌合させることにより、装着される。ロータ3は、脱着時において、工具溝32に差し込まれる工具の回転操作により回転可能である。【選択図】図1
