Electrical switching device with pyrotechnic activation feature
The patent US12040145B2 describes an innovative electrical switching device designed to manage current flow through a housing containing fixed and movable contacts. The device features at least one fixed contact with two portions angled relative to each other, and a movable contact that can transition between a closed state, allowing current flow, and an open state, interrupting it. The transition between these states is facilitated by a triggering device that responds to levitation caused by elevated current signals. This levitation occurs due to electromagnetic forces generated at the contact points between the fixed and movable contacts, which can lead to arcing and increased resistance, ultimately activating the triggering mechanism.
Additionally, the patent outlines various configurations for the triggering device, which may include pyrotechnic elements and passive trigger switch structures. These components are designed to interact with the fixed and movable contacts to ensure reliable operation of the switching device. The claims also specify the arrangement of the contacts, emphasizing the importance of their geometric relationships, such as the 90-degree angle between the portions of the fixed contact and the linear alignment of the movable contact. This design aims to enhance the efficiency and responsiveness of the electrical switching device, making it suitable for applications requiring precise control of electrical currents.
