    • A single vibration sensor producing multistage outputs corresponding to various vibrational acceleration values is disclosed. This vibration sensor is the type in which vibrational acceleration causes a movable gravitation element to move, and the movement of the element exerts pressure on a plunger which actuates a switch mechanism and outputs a signal. A feature of this vibration sensor is the switch mechanism includes a number of discrete switch units each having a different operating sensitivity. The switch units have a number of movable members which are displaced by the plunger when the vibrational acceleration causes the movable gravitation element to move, and a number of fixed contacts corresponding to these movable members with which the movable contacts come in contact. The spatial relationship of the fixed contacts with respect to the movable members is a feature which determines the operational sensitivity.
