Abstract:
1. A jerking-initiated switch mountable on and to be disposed in electric contact with a substrate, said jerking-initiated switch comprising: an insulating frame which includes an electrically conductive ball disposed to be rollable along said rolling path between first and second switching positions where said switch is in first and second switching states, respectively; a first interconnecting member which is disposed adjacent to said first lateral side, and which extends in the first transverse direction to terminate at front and rear first joining ends; front and rear first shank members which are made from an electrically conductive material, which are respectively connected to said front and rear first joining ends, and which extend in the second transverse direction to respectively terminate at front and rear first contact terminals that extend outwardly of said frame to electrically contact the substrate; at least one second shank member which is made from an electrically conductive material, and which is secured to said base wall, said at least one second shank member being disposed to extend in the second transverse direction to terminate at a second contact terminal that extends outwardly of said frame to electrically contact the substrate, and at a second joint that is opposite to said second contact terminal; and at least one first limb member which is integrally formed with and which extends from said second joint in the longitudinal direction to form a first guideway along said rolling path such that said ball can slidably contact said at least one first limb member, and which extends towards said front and rear first shank members to terminate at a first threshold region, said first threshold region being spaced apart from said front and rear first shank members, and corresponding to the first switching position, said at least one first limb member having a first idle region which is configured to correspond to the second switching position such that once said ball is caused to displace from one of said first idle and threshold regions to the other of said first idle and threshold regions in response to a jerking action, said switch is placed in one of the first and second switching states.
