ABSTRACT:
A tilt switch includes a switch casing which confines a chamber therein. First, second and third conductive terminals are provided on sides of the chamber. A movable conductor moves inside the chamber. The switch casing is turnable between a first switch position, wherein gravity acts on the movable conductor so as to place the movable conductor between the first and second conductive terminals to make electrical connection between the first and second conductive terminals, and to break electrical connection between the first and third terminals, and a second switch position, wherein gravity acts on the movable conductor so as to move the movable conductor between the first and third conductive terminals to make an electrical connection and to break electrical connection between the first and second conductive terminals. The movable conductor may include three contacting ball members movable in two communicating chambers.
