Joystick, controller, and arcade machine

A joystick, comprising:

• a base;
• a joystick shaft in operable connection with the base;
• a trigger member and a limit member each extending around a portion of an outer surface of the joystick shaft;
• four micro-switches fixed on the base, wherein the four micro-switches are respectively located in one of four cardinal directions of the trigger member, and four ordinal directions are respectively formed between every two adjacent micro-switches of the four micro-switches, wherein each of the four micro-switches is a mechanical-shaft-key switch and comprises a fixed seat and a key shaft protruding from the fixed seat, and wherein the key shaft is configured to be pressed by the trigger member to trigger the micro-switch;
• and
• a retaining ring configured to limit rotation angles of the joystick shaft,
• wherein the joystick shaft has a cardinal rotation angle and an ordinal rotation angle, the cardinal rotation angle being a maximum rotation angle of the joystick shaft in any of the four cardinal directions, and the ordinal rotation angle being a maximum rotation angle of the joystick shaft in any of the four ordinal directions.
