1. An electrical switching device, comprising:
a hermitically sealed housing comprising a cup with a header;
a movable contact disposed in the hermetically sealed housing, the movable contact configured to move between a first position and a second position;
a solenoid disposed in the hermetically sealed housing and coupled to the movable contact, the solenoid configured to move the movable contact to the first position from the second position when energized;
a first fixed contact and a second fixed contact spaced from the first fixed contact, the first fixed contact and the second fixed contact passing through the header such that portions of the first fixed contact and the second fixed contact protrude from the header and extending into the hermetically sealed housing such that, in the first position, the movable contact contacts the first fixed contact and the second fixed contact to allow current flow between the first fixed contact and the second fixed contact and, in the second position, the movable contact is spaced from at least one of the first fixed contact and the second fixed contact;
a first eyelet configured to seal the first fixed contact relative to the hermetically sealed housing and a second eyelet configured to seal the second fixed contact relative to the hermetically sealed housing, the first eyelet and the second eyelet mounted to the portions protruding from the header; and
a metal ring surrounding at least one of the first eyelet or the second eyelet and attached to a side surface of the at least one of the first eyelet or the second eyelet for attachment to the header.
