<p>A modular three position vacuum isolator switch that is operable to connect a moveable contact to either of two stationary contacts or an intermediate position which is out of electrical engagement with either of the stationary contacts. One of the stationary contacts is grounded and the other is connected to two electrical connectors. One of the two electrical connectors is connected to a first line source 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 moveable contact is connected to a 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.</p> |
