Abstract
Disclosed herein are contactor devices, for example, devices that can be utilized as switching elements, comprising fixed contacts that are electrically isolated from one another and one or more moveable contacts that are configured to electrically contact the fixed contacts to provide an electrical connection between them. Movement of the fixed contacts into and out of electrical contact with the fixed contacts controls flow of electricity through the devices. The contactor devices also include pyrotechnic disconnect elements, which function as a circuit break or fuse-like element to protect against overcurrent. When the electrical current through the contactor device reaches a threshold level, a pyrotechnic charge activates, permanently forcing the moveable contacts out of electrical contact with the fixed contacts.
