A joystick 3 includes a circuit board 1, a thin film circuit 2 arranged on the circuit board 1, a joystick 3 on the thin film circuit 2, and a spacer 4 arranged between the thin film circuit 2 and the circuit board 1. By the joystick 3, the thin film circuit 2 is in contact with the circuit board 1 so that resistor are connected in parallel so as to reduce the resistance to control the direction and speed of the cursor precisely. As the rod 37 is pushed by an outer force, the pit 36 on the movable body 34 presses one of the joint points 12 and 22. Then, the joint points 12 and 22 will transfer a signal of the resistor, and thus, the movement of the control cursor can be controlled.
