Abstract

5562. Price, S. L. March 5. Mercury switches. - An electric switch, of the type in which the circuit is completed in a rotating vessel by the displacement of mercury under centrifugal action, comprises two or more chambers or a divided chamber c, d adapted to be partly filled with mercury and provided with more than two contacts so arranged in series that the circuit remains broken in any stationary position of the switch and is only completed by centrifugal action. In the form shown, a pair of contacts is provided in each chamber, one contact f, h in each chamber being connected to slip-rings k, m, the other contacts g, j being connected to each other. The vessel is mounted in a casing b on a shaft a. The switch is especially adapted for use in lighting- circuits of railway and other vehicles where a generator driven from the axle of the vehicle is cut-in at a certain speed.
