Abstract:
1. A rolling-ball switch adapted to be fixed on a circuit board, said rolling-ball switch comprising: a housing defining a chamber and having a bottom wall provided with four spaced-apart through holes arranged in a rectangular array; two conducting units respectively having plate-like connecting members disposed in parallel below said bottom wall, each of said connecting members having at least one abutment surface in abutment with said bottom wall, a first connecting surface opposite to said abutment surface, and second and third connecting surfaces extending between said abutment surface and said first connecting surface, each of said conducting units further including two terminals extending upwardly from said abutment surface of one of said connecting members into said chamber and passing respectively through two of said through holes, said two terminals being spaced apart from each other in a longitudinal direction of a corresponding one of said connecting members, said second and third connecting surfaces being opposite to each other in said longitudinal direction, said first, second, and third connecting surfaces being adapted to be selectively fixed on the circuit board; and a conductive ball disposed movably in said chamber to move toward or away from said terminals.
