Isolator switch
First Claim
1. An isolator switch modulea 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.

Abstract
A modular three position vacuum isolator switch that is operable to connect a stationary contact to either of two moveable contacts or an intermediate position which is out of electrical engagement with either of the moveable contacts. One of the moveable contacts is grounded and the other is connected a power source. The stationary contact is connected to two electrical connectors. One of the two electrical connectors is connected to a breaker and the second is connected to a corresponding input on a second similar isolator switch model, which itself is connected to a second line source. The stationary contact is connected to the circuit interrupter for connecting the circuit interrupter to either of the two line sources, to ground, or to isolate the circuit interrupter by placing the isolator switch module in the intermediate position.
