PURPOSE:To accurately sense collision in multiple directions based on breakage conditions of a body by cutting a narrow wire with a cutter to bring a movable contact into contact with a fixed contact with a spring when one part of body to which a case is fixed and another part of body to which a part of a narrow wire is connected are displaced relatively. CONSTITUTION:Fixed contacts 12, 13 are arranged at one side in a case 11 fixed to one part of a body and a movable contact 15 which abuts on the fixed contacts 12, 13 when it is pushed by a spring 14 is arranged in a face-to-face relation therewith. A narrow wire 16 being connected to the movable contact 15 at its end while being fixed to another part of body, at its another end extending through the case 11 pulls the movable contact 15 to separate it from the fixed contacts 12, l3, is provided, and a cutter 17 to cut the narrow wire 16 when the wire 16 is dislocated in the directions other than the longitudinal direction is provided. When the part to which the case 11 is fixed and the part to which the end of the narrow wire 16 is fixed are displaced relatively after the body is broken, the narrow wire 16 is cut by a cutter 17 so that collision is sensed.
