Passive triggering mechanisms for switching devices incorporating pyrotechnic features

The invention relates to passive triggering mechanisms for 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, the reed switch responds to the increased current and then a signal with the increased current can be used to activate the pyrotechnic feature. In other embodiments, the reed switch uses a power signal from an auxiliary power source to activate the pyrotechnic feature. 本发明涉及用于包含烟火特征的切换装置的无源触发机构。本文公开了用于激活电气切换装置(例如接触器装置和熔丝装置)内的烟火特征的无源触发机构。烟火特征的激活被配置为改变切换装置的内部部件的配置并防止电流流过该装置。在一些实施方式中，触发机构包括响应磁场的特征，例如簧片开关。在一些实施方式中，簧片
