Abstract: A carrier sub-assembly for an electrical relay device includes a plunger and a shaft. The plunger is formed of a ferromagnetic material. The plunger has a generally cylindrical shape extending between a top side and a bottom side of the plunger. The shaft extends between a contact end and an opposite plunger end. The shaft is directly secured to the plunger without a discrete component between the shaft and the plunger securing the shaft to the plunger. The shaft and the plunger are configured to move together within the electrical relay device. A segment of the shaft including the contact end protrudes from the top side of the plunger for securing to a movable contact of the electrical relay device.

Abstract: An electrical relay device includes a housing, a wire coil, an actuator assembly, and a shell. The housing extends between a closed end and an open end and defines a chamber. The wire coil and the actuator assembly are within the chamber. The actuator assembly is configured to move between a first position, in which a movable contact is spaced apart from at least one stationary contact, and a second position, in which the movable contact engages the at least one stationary contact, based on a magnetic field induced by current through the wire coil. The shell seals the open end of the housing to seal the chamber. The shell has a pressure relief valve in flow communication with the chamber. The pressure relief valve is configured to open in response to a pressure within the chamber exceeding a threshold set pressure to reduce the pressure within the chamber.
