Abstract
A sensor switch includes a base unit having bottom, top and intermediate layer assemblies cooperating with each other to define a chamber. The intermediate layer assembly has an intermediate layer inner peripheral surface. A conducting unit includes a plurality of inner and outer conducting elements. Each inner conducting element has a first conducting section. The first conducting sections of the inner conducting elements are disposed on the intermediate layer inner peripheral surface in an angularly spaced apart manner. Each outer conducting element is connected to the first conducting section of a corresponding inner conducting element. A conductive member is rollably disposed in the chamber.
Claims13
A sensor switch comprising:
- a base unit made from a plurality of raw ceramic blanks that are sintered after being stacked, said base unit including a bottom layer assembly, a top layer assembly opposite to said bottom layer assembly in a top-bottom direction, and an inter-mediate layer assembly connected between said bottom layer assembly and said top layer assembly and cooperating with said bottom layer assembly and said top layer assembly to define a chamber having an axis parallel to the top-bottom direction, said intermediate layer assembly having an intermediate layer inner peripheral surface surrounding an intermediate part of said chamber, one of said bottom layer assembly and said top layer assembly having a first mounting surface disposed on an outer side thereof and distal to said chamber;
- a conducting unit made of metal and including a plurality of inner conducting elements and a plurality of outer conducting elements, each of said inner conducting elements having a first conducting section, said first conducting sections of said inner conducting elements being disposed on said intermediate layer inner peripheral surface in an angularly spaced apart manner, each of said outer conducting elements being connected to said first conducting section of a corresponding one of said inner conducting elements and having a mounting portion said mounting portions of at least some of said outer conducting elements being disposed on said first mounting surface;
- and
- a conductive member made of metal and rollably disposed in said chamber;
- wherein said conductive member contacts any two adjacent ones of said first conducting sections when said sensor switch is tilted.
