ABSTRACT:
A jerking-initiated switch includes first and third shank members secured to an insulating frame and spaced apart from each other, and at least one second shank member interposed therebetween. Each of the shank members has a contact terminal extending outwardly of the frame to electrically contact a substrate. Two limb members are integrally formed and are connected to the second shank member, and extend towards the first and third shank members, respectively, so as to form guideways that an electrically conductive ball is rollable thereon. Each guideway has idle and threshold regions at different heights such that the ball is caused to displace from one of the idle and threshold regions to the other of the idle and threshold regions in response to a jerking action, thereby placing the switch in one of the first and second switching states.
