ABSTRACT:
An inertia switch resettably breaks an electrical contact upon a change in the momentum of the switch body above a predetermined level or upon inversion of the switch body. An inertia sensing pendulum detects momentum changes upon the switch body and upwardly moves an actuator shaft upon a momentum change above a level determined by a biasing mechanism. The actuator shaft is coupled to an electric contact mechanism, which resettably interrupts an electrical connection upon the upward movement of the actuator shaft. A moveable mass in a cylindrical cavity is coupled to the contact mechanism and causes the electrical connection to be broken in response to an inversion of the body. A reset mechanism coupled to the contact mechanism, reestablishes the interrupted electrical connection when manual force is applied to the reset means.
