The Switchboard

The various details of the switchboard manufactured and used in connection with the plants of the Mather System have been carefully developed, and are so arranged that the various combinations can be handled with the least complication.

The ampere-meters, for measuring the quantity of current, and the volt-meters, for measuring the electromotive force or pressure, are made on the steam-gauge pattern, mounted in polished brass cases in the most substantial manner.

The various switches for handling the current are also made of polished brass and have ample contact surfaces and carrying capacity; they are mounted upon slate or marble bases, and are therefore incombustible.

The rheostats used by the Mather System are of the simplest construction, not liable to get out of order, and are also incombustible. The above instruments, when systematically and properly arranged, make a very handsome appearance, as will be seen from the illustrations of switchboards already installed, in this pamphlet.

The Mather Meters

The accompanying cuts illustrate the Mather Voltmeters and Ammeters. In form they are of the " steam-gauge " pattern.

All instruments are finely finished, the cases being highly polished and lacquered, and present a very handsome appearance.

Great care is taken in their calibration, and their accuracy is guaranteed. These instruments are made for any reading up to six hundred volts and five hundred and fifty amperes. Special sizes to order. They may be left in or out of circuit as desired.
