Abstract: A tilt ball switch includes a cover, a first positioning unit, a plurality of conductive members, a conductive ball, a base wall, a surrounding wall that extends from a periphery of the base wall, and an opening that is formed at one end of the surrounding wall opposite to the base wall. The cover closes the opening, and cooperates with the base wall and the surrounding wall to define a receiving space. The first positioning unit is disposed in the receiving space, and is positioned between the base wall and the cover. The conductive ball is convertible between a conducting state, in which the conductive ball is in contact with at least two of the conductive members, and a non-conducting state, in which the conductive ball is spaced apart from the conductive members.
