A jerk-initiated switch includes a housing having an inner housing wall which defines an accommodation chamber therein. First and second terminals are disposed to define a switching action enabling path of a straight length that crosses the accommodation chamber. A ball member and a momentum reducing member are disposed in the accommodation chamber. When the housing is jerked, the ball member is displaceable from a first position, where the ball member is disposed to interrupt the switching action enabling path to establish a first electric switching state, to a second position, where the ball member is disposed outside the switching action enabling path to establish a second electric switching state. The momentum reducing member is configured to yield under impact from the ball member to reduce the momentum of the ball member when the ball member is displaced from the first position to the second position.
