Abstract:
Electrical switching device are disclosed having a housing with internal component within the housing. The internal components comprise contacts configured to operate, to change the state of the switching device from a closed state, allowing current flow through the switching device to an open state which interrupts current flow through the switching device. A pyrotechnic feature is included that is configured to interact with the internal components to transition the switching device from the closed state to the open state when the pyrotechnic feature is activated. The pyrotechnic feature is configured to trigger in response to levitation between the contacts at elevated current signal flowing through the switching device.
