  • Carrier sub-assembly for an electrical relay device
    Patent number: 9916952
    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.
