Dumping switch

The utility model discloses a toppling switch which comprises a shell, a movable cavity is arranged in the shell, a gravity ball located in the movable cavity is movably arranged in the shell, the shell is provided with a microswitch capable of being in contact with the gravity ball, and a flexible buffer structure is arranged on the inner wall of the movable cavity and/or the outer surface of the gravity ball. According to the dumping switch with the structure, when the gravity ball impacts the inner wall of the movable cavity, the flexible buffer structure can quickly reduce the impulse of the gravity ball, prolong the contact time of the gravity ball and the inner wall of the shell, prevent the gravity ball from generating large impact on the inner wall of the shell, reduce the use noise of the dumping switch and reduce the abrasion of the gravity ball; and the service life of the dumping switch is prolonged. 本实用新型公开了一种倾倒开关，包括：壳体，所述壳体内设有活动腔，所述壳体内活动设置有位于所述活动腔中的重力球，所述壳体设有能够与所述重力球相接触的微动开关，所述活动腔的内壁和/或所述重力球的外表面
