• a housing having an accommodating space, where the housing is provided with a recess around the accommodating space, and a first electrode and a second electrode are disposed on a bottom surface of the recess;
• a bezel, where at least one part of the bezel is disposed in the recess, wherein when the bezel is located at a first position of the recess, the first electrode and the second electrode are conductively connected;
• and when the bezel is located at a second position of the recess, the first electrode and the second electrode are conductively disconnected;
• and
• an elastic member disposed on the bottom surface and having a first end connected to the first electrode,
• wherein one end of the bezel facing the bottom surface of the recess is provided with a protruding portion;
• when the bezel is located at the first position, the protruding portion presses the elastic member, and a second end of the elastic member is connected to the second electrode;
• and when the bezel is located at the second position, the protruding portion is away from the elastic member, and the second end of the elastic member is separated from the second electrode.
