Inertia switch

Abstract

Abstract AN INERTIA SWITCH INCLUDING A MASSIVE INERTIA ELEMENT MOVABLE THROUGH AN ARTICULATED CONNECTION COLLAPSIBLE FROM AN EXTENDED CONDITION IN RESPONSE TO ABRUPT CHANGES IN VELOCITY TO ACTUATE THE SWITCH. A PAIR OF PIVOTAL ARMS OF THE ARTICULATED CONNECTION EXTEND, IN A STABLE POSITION, IN END-TOEND RELATIONSHIP BETWEEN A MOUNTING POINT AND A RESILIENT CONDUCTIVE MEMBER. THE PIVOTABLE ARMS ABUT AT PLANAR END SURFACES THEREOF, PROPPING THE RESILIENT MEMBER IN ITS UPPERMOST POSITION. THE INERTIA ELEMENT IS SUPPORTED ON THE UPPERMOST ARM AND FORCES APPLIED TO THE PIVOTABLE ARMS IN THEIR STABLE POSITION BY THE BIAS OF THE RESILIENT MEMBER AND THE WEIGHT OF THE INERTIA ELEMENT EXTEND ALONG THE ARMS TO THE MOUNTING POINT. ABRUPT VELOCITY CHANGES PIVOT THE ARMS FROM THEIR STABLE ALIGNMENT UNDER THE INFLUENCE OF THE INERTIA ELEMENT, ALLOWING MOVEMENT OF THE RESILIENT MEMBER FOR SWITCH ACTUATION. RESETTING LEVERS ARE ENGAGEABLE WITH THE INERTIA ELEMENT FOR RETURNING THE INERTIA ELEMENT AND PIVOTABLE ARMS TO THEIR CENTRAL STABLE POSITION AND CURRENT BYPASS PROVISIONS PROTECT THE RESILIENT MEMBER FROM EXCESSIVE CURRENTS.
