Under these conditions all the busses can be tied together by tie switches, or all feeders can be thrown on one bus. W T here the feeders themselves have to be supplied with more than two potentials during the load fluctua- tions on the station, several forms of switches have been devised for this purpose. The simplest form is a double pole double throw switch, having each blade on an indepen- dent handle ; in this way a feeder can be supplied from any of four potentials, and also two busses ca...n be connected together by this switch at low loads. See Fig. 83. The radial form of switch for the same purpose has different bus bars con- nected to clips and disposed concentrically around the centre ; the switch plate is pivoted so that it can be thrown in on any of these busses when swung around in position. For this construction, see Fig. 84.
Another form has been developed for this purpose, where the switch blade is detachable, and can be engaged with several terminals which align with the different bus terminals 83 107 LOW TENSION CENTRAL STATION SWITCHBOARDS and the movable blade inserted ; in this way the feeder can be con- nected to any bus.
