PROBLEM TO BE SOLVED: To provide a key operated selector switch capable of allocating plural operation modes in which one or more selection operations are allowed depending on one model number of a key operated selector switch.SOLUTION: The key operated selector switch has a plural steps of rotation range restriction mechanisms which are arranged along an insertion direction of a key between a rotor 81 and a rotor case 7. Depending on an engagement state of the inserted key with the engaged portion in the rotor 81, the rotation range restriction mechanisms allows the rotor 81 to be rotated overriding a protruding wall which is formed on an inner wall of the rotor case 7, or for restricting the rotor 81 from being rotated overriding the protruding wall. The rotation range restriction mechanism in the respective steps has a rotation angle range up to each protruding wall, which is different from each other. The rotor 81 is arranged to be rotated up to a minimum rotatable range of the rotating range limiting mechanism in each step. The rotatable range is determined by the state of engagement with the engaged portion of the key corresponding to the rotating range limiting mechanism of each stage. The rotor 81 is arranged to output a contact point according to the rotation angle which is made within the maximum rotatable range.SELECTED DRAWING: Figure 6 【課題】１つのキー操作型セレクタスイッチでキーの型番毎に１以上の選択操作が可能な複数の操作モードの割振が可能なキー操作型セレクタスイッチを提供すること。【解決手段】ロータ８１とロータケース７との間に設けられ、前記ロータ８１に挿入されたキーの被係合部への係合状態に応じて、前記ロータケース７の内壁に設けられた突起壁を越えて前記ロータ８１の捻回を可能にし、または、前記突起壁を超えた前記ロータ８１の捻回を制限する捻回範囲制限機構を前記キーの挿入方向に沿って複数段設け、各段の捻回範囲制限機構は、各突起壁までの捻回角度範囲が異なり、前記ロータ８１は、各段の捻回範囲制限機構に対応する前記キーの被係合部との係合状態によって決定される各段の捻回範囲制限機構の捻回可能範囲のうちの最小の捻回可能範囲を前記キーに対する最大の捻回可能範囲とし、最大の捻回可能範囲内で捻回された捻回角度に応じた接点出力を行う。【選択図】図６
