Computer joystick with a removable joystick handle

A computer joystick comprising:

• a chassis having an opening on its top;
• a joystick mechanism having two shafts perpendicular to each other and rotatably installed in the chassis, and a control handle rotatably installed in the opening of the chassis for interacting with the two shafts so that movements of the control handle can be converted into corresponding rotations of the two shafts;
• two sensors installed in the chassis for detecting rotations of the two shafts separately and generating corresponding rotation signals;
• a joystick handle having a locking means installed on its bottom end for removably mounting the joystick handle to a top end of the control handle so that the joystick handle coupled with the control handle can be used to drive the two shafts of the joystick mechanism, the locking means of the joystick handle comprising a specifically shaped recess for matching and removably mounting the top end of the control handle, the joystick handle further comprising at least one control button, an electrical wire having a first end connected to the button and a second end connected with an electric plug, and an elastic detention means installed inside the recess, and the control handle comprising a corresponding receiving means at its top end for receiving the detention means wherein the elastic detention means of the joystick handle is engaged with the receiving means of the control handle to reliably hold the joystick handle on top of the control handle when the joystick handle is mounted to the control handle;
• and
• a control circuit wired to the two sensors for receiving rotation signals generated by the two sensors, the control circuit further comprising a socket for removably connecting the plug of the joystick handle so that control signals generated by the button can be received by the control circuit.
