A deceleration impact detector for detecting a vehicle collision or the like is composed of a rotor having an eccentric gravity center, a spring biasing the rotor to its initial position, a cam connected to rotor, and a pair of contacts consisting of a movable contact and a stationary contact. The rotor rotates together with the cam when a deceleration exceeding a predetermined level is imposed on the rotor. The pair of contacts are closed by the cam thereby to generate an electrical signal to inflate an air-bag. The movable contact is made of a resilient leaf spring, while the stationary contact is made of a plate having a high rigidity, so that resonant vibrations of the stationary contact otherwise caused by a high deceleration impact are avoided.
