ABSTRACT:
An omni directional impact-activated trigger assembly. The trigger comprises a switch mechanism that controls the activation of an operation, such as an electrical circuit, so that movement of the switch opens or closes the circuit. One specific application of this trigger is to activate an ignition shut-off circuit in a vehicle or some other electrical device in response to an impact. A spherical weight is suspended for omni directional movement by flexible suspension ligaments that transmit movement of the weight to a contact member that engages the switch. Rapid acceleration or deceleration of the frame or any impact received by the frame will register as a movement of the sphere, which in turn causes movement of the contact member toward an engaged position. An adjustable biasing member is tensioned to control the degree of impact necessary to activate the switch.
