PASSIVE TRIGGERING MECHANISMS FOR USE WITH SWITCHING DEVICES INCORPORATING PYROTECHNIC FEATURES

Disclosed herein are passive triggering mechanisms for activation of pyrotechnic features within electrical switching devices, such as contactor devices and fuse devices. The activation of the pyrotechnic features is configured to change the configuration of the internal components of the switching device and prevent current flow through the device. In some embodiments, the triggering mechanisms comprise features that respond to a magnetic field, such as a reed switch. In some embodiments, threshold strength of a magnetic field needed to trigger the passive triggering mechanism, which corresponds to a threshold level of current running through the switching devices indicating a dangerous overcurrent, can be adjusted based upon the distance between the passive triggering mechanism and a portion of the device such as a power terminal or feature connected to a power terminal.
