Abstract: An assembly for engaging an electromagnetic actuator comprising a first shaft having a first link and a second shaft having a second link connected by a biasing assembly configured to rotate between an initial and a final position. A contact arm of the second shaft advances a sliding armature of the electromagnetic actuator from an activated state to a deactivated state such that the assembly prevents the electromagnetic actuator from returning to the activated state. The biasing assembly has a toggle-over position in which a biasing force rotates the contact arm from the toggle-over position to the final position.

Abstract: A solid dielectric deadfront electrical switch assembly having a switch contact assembly. The switch contact assembly can include an upper insulative diaphragm, a male pin contact having an insulating tip and an isolating sleeve, a primary contact, a lower insulative diaphragm, and a female socket contact. The upper insulative diaphragm, isolating sleeve, and insulating tip can assist in electrically isolating the male contact pin when the electrical switch assembly is in an open condition. Further, the upper insulative diaphragm can be separated from the female socket contact, and/or a female-contact insulating sleeve, by a gap chamber that utilizes air as an insulator. The lower insulative diaphragm can be configured to engage a drive rod that is used to axially displace the male pin contact between open and closed positions in a manner that may prevent arcing between the switch contact assembly and a base plate of a switchgear.
