Switching devices incorporating rupture disk

A contactor device, comprising:

• a hermitically sealed housing;
• internal components within the hermetically sealed housing, the internal components configured to change the state of the contactor device between a closed state and an open state in response to input, the internal components generating arcing pressure when changing states from closed to open;
• and
• a pressure relief mechanism to allow said arcing pressure to escape from the housing, the pressure relief mechanism comprising a weakened portion of a bottom of the housing,
• wherein the bottom of the housing has a first thickness and the weakened portion comprises, at least in part, a portion of the bottom having a second thickness thinner than the first thickness, the portion of the bottom comprising, at least in part, a scored portion, and
• wherein, in response to the arcing pressure, an opening is formed at the weakened portion.

An electrical switching device, comprising:

• a hermitically sealed housing comprising a rupture disk hole formed in a floor of the hermetically sealed housing;
• internal components within the hermetically sealed housing, the internal components configured to change the state of the electrical switching device from a closed state to an open state in response to input;
• contact structures electrically connected to said internal components for connection to external circuitry;
• and
• a rupture disk sealing the rupture disk hole, wherein, in response to an increased air pressure inside the housing and acting on the rupture disk, the rupture disk at least partially separates from the housing to allow the increased air pressure to escape from the housing through the rupture disk hole.
