ABSTRACT:
A jerking-initiated switch includes two first shank members and two second shank members secured to first and second lateral sides of a base wall of an insulating frame to define a rolling path for rolling of an electrically conductive ball therealong. Two limb members are respectively and integrally formed with, and extend from, the second shank members to form a guideway along the rolling path such that the ball can slidably contact the limb members, and extend towards the first shank members to terminate at threshold regions that are spaced apart from the first shank members. The limb members have idle regions on the rolling path. Once the ball is jerked to displace from one of the idle and threshold regions to the other, the switch is placed in one of the first and second switching states.
