A miniature joystick model 802-2 to indicate the direction of travel or to manipulate the actuator in two axes requires soldering in a printing plate. It is so small that it's comfortable to move it with your thumb. The manipulator head is covered with a special material that increases the friction between it and the finger. The deflection of the twig has a mechanical angle of + 30 degrees. The element of the sensor is a potentiometer with a value of 10 microns. Similar manipulators are used in youth games such as Nintendo. It weighs only 6g. The 802-3 version has a built-in button.
