A durable, reliable and comfortable joystick for use in precision applications such as controlling a surveillance camera. The joystick of the present invention incorporates mechanical linkages that convert the user's motion into the rotation of three different resistive potentiometers, one for each of 3 axes of movement (X, Y and Z). The potentiometers and linkages for the X- and Y-axes are incorporated into the joystick base, and the potentiometer and linkage for the Z-axis is uniquely incorporated into the joystick handle. Rotation of the handle is restricted in order to prevent damage to the internal parts and preserve the life of the joystick.
