A direction sensor includes two electrode guides, at least six contact pins, a moving member and a signal processing circuit. The two electrode guides are formed with a gap. The two electrode guides and the at least six contact pins define a space. The moving member is restricted to move in the space. The two electrode guides are electrically connected to one signal terminal of the signal processing circuit, respectively, and the at least six contact pins are electrically connected to another signal terminal of the signal processing circuit, respectively. A direction is sensed after the moving member moves in the space according to a sensed direction and contacts with the contact pin corresponding to the sensed direction below, so that one of the electrode guides and the contact pin corresponding to the sensed direction below form a sensing signal loop through the moving member.
