Rotating switch mechanism with locking mechanism

An electronic device, comprising:

• a rotating switch mechanism for switching a conduction state of a predefined electronic circuit corresponding to a rotating operation of a rotating operation part rotatably provided on a housing on a predefined rotational axis;
• a locking mechanism for locking the rotation of the rotating operation part relative to the housing;
• and
• a switching member for switching an operating state and a non-operating state of the electronic device;
• wherein
• the operating state and the non-operating state are switchable by the switching member, and the locking mechanism locks the rotation of the rotating operation part relative to the housing when the electronic device is put into the non-operating state by the switching member and does not lock the rotation of the rotating operation part relative to the housing when the electronic device is put into the operating state by the switching member,
• the switching member is movable between the operating position for putting the electronic device into the operating state and the non-operating position for putting the electronic device into the non-operating state, and
• the switching member releases the lock of the rotation of the rotating operation part relative to the housing by interference with the locking mechanism when the switching member is in the operating position, and the switching member locks the rotation of the rotating operation part relative to the housing by being released from interference with the locking mechanism when the switching member is in the non-operating position.
