An inertia switch comprises a mass which actuates an electrical switch assembly upon being subjected to a predetermined velocity change. The switch assembly comprises a set of two electrical contacts that are disposed within a switch enclosure in resiliently deflected, spaced apart conditions so as to make the set normally open when the inertia switch is in a quiescent condition. During the occurrence of such a predetermined velocity change, the mass operates an actuator of the electrical switch assembly to cause one contact to be further resiliently deflected and engage and also further resiliently deflect the other contact thereby creating switch closure indicating that the predetermined velocity change has occurred.

In an inertia switch device in which a normally restrained inertial mass overcomes its restraint in response to a predetermined velocity change, such as a deceleration, to displace the actuator of an electrical switch assembly via which the device gives a signal of the occurrence of such a predetermined velocity change, the improvement which comprises said electrical switch assembly comprising a contact enclosure containing a set of two, resiliently deflectable electrical contacts both of which contacts are disposed in resiliently deflected conditions within said contact enclosure to a predetermined spacing distance so long as the device does not experience such predetermined velocity change, said actuator being disposed on said electrical switch assembly for displacement along a predetermined path of travel with respect to said set of contacts for acting upon said set of contacts when such predetermined velocity change occurs, one of said two electrical contacts being further resiliently deflected in response to displacement of said actuator along said predetermined path of travel upon occurrence of such predetermined velocity change to engage and also further resiliently deflect the other contact of said set thereby creating switch closure of said set causing the device to give a signal indicative of the occurrence of such predetermined velocity change.
