An acceleration switch that improves detection sensitivity without being enlarged. The acceleration switch includes a switch body, a fixed electrode arranged in the switch body, and a movable weight arranged in the switch body. The movable weight is displaced when subjected to acceleration. The movable weight includes a movable electrode that contacts the fixed electrode when the movable weight is displaced, and a pair of beams connecting the movable weight and the switch body. The beams pivotally support the movable weight and extend into recesses formed in the movable weight.
