ABSTRACT:
A mechanical sensor comprises a casing having an axis, an inertia body received in the casing for displacement axially thereof, and an output member received in the casing for displacement axially thereof and having a portion extending out of the casing so as to transmit displacement of the output member to the outside of the casing. A set spring biases the inertia body to a set position in the casing. A stopper is received for axial displacement within the casing, and an actuator spring is engaged between the inertia body and the stopper and is also engageable with the output member to cause it to displace upon displacement of the stopper. Latch members movably coupled to the inertia body are engaged between the stopper and the casing in the absence of displacement of the inertia body in response to a predetermined acceleration of the inertia body so that the stopper stores energy in the actuator spring. The latch members are releasable from engagement between the casing and the stopper upon displacement of the inertia body by a predetermined acceleration to enable release of the energy of the actuator spring and displacement of output member by the actuator spring.
