Abstract
A rolling-ball tilt switch includes a conductive housing having an inner surface that surrounds a longitudinal axis and that defines a roller cavity, an insulating seat inserted into the roller cavity, a conductive terminal having a protruding section extending through the insulating seat into the roller cavity, and a ball unit disposed in the roller cavity and moveable between a conducting position and a non-conducting position. The longitudinal axis and an extension of a surface portion of the inner surface of the conductive housing cooperatively define a first angle that ranges from 2 to 12 degrees.
