PROBLEM TO BE SOLVED: To detect the weight level and the seating position of an occupant. SOLUTION: A load switch 5 furnishes four membrane switches with different operating loads, and actuators 61 to 64 corresponding to the membrane switches. The membrane switch 94 on a base consists mainly of a contact 901 and a metal disk 900, and has a gap H with the contact. The actuator 64 is inserted to a hole 7a formed to the upper side 71 of a housing 7 from the inner side, and it furnishes a convex 6b, and a locking part 6c larger than the diameter of the hole 7a. When a specific load is operated to the upper surface 6d of the actuator 64, the actuator 64 is displaced to the lower side to deform the disk 900 elastically, and the disk 900 and the contact 901 are contacted, so as to output an electric signal to the outer side through a lead line 10. |
