Isolator switch

An isolator switch module

• a sealed isolator switch container housing a medium having a lower electrical conductivity than air, wherein the isolator switch container is impermeable to the medium;
• a first movable isolator switch contact sealed within the container;
• a first electrical isolator switch conductor connected to the first movable isolator switch contact at the one end, sealably penetrating the container and terminating at the other end in a first electrical isolator switch connector;
• a second movable isolator switch contact sealed within the container;
• a second electrical isolator switch conductor connected to the second movable isolator switch contact at one end and sealably penetrating the container and terminating at the other end in a second electrical isolator switch connector;
• stationary isolator switch contact means sealed within the container;
• a third electrical isolator switch conductor connected to the stationary contact at one end, sealably penetrating the container and terminating at the other end in a third electrical switch isolator connector;
• said first moveable isolator switch contact being moveable between a first first moveable isolator switch position in which it makes electrical contact with said stationary isolator switch contact means and a second first moveable isolator switch position in which it does not, and said second moveable isolator switch contact being moveable between a first second moveable isolator switch position in which it makes electrical contact with said second stationary isolator switch contact means and a second second moveable isolator switch position in which it does not;
• and
• means for moving either the first, second or both moveable isolator switch contact means between the first and second positions, thereof, in response to a given operator action.
