Title: Inertia switch assembly

Abstract: In a housing having a cylindrical bore, an inertia sensing weight is slidably disposed. At one end of said weight, a movable contact is normally carried in complementary engagement thereby separating from a stationary contact. When the weight moves under acceleration or deceleration, the movable contact accompanies the weight until the movable contact abuts the stationary contact. In the illustrated embodiment there is a second stationary contact normally separated from the first one. The movable contact, when closing, abuts both of them, making an electrical circuit therebetween.
