Abstract

12,919. British Thomson-Houston Co., and Wallace, J. M. May 29. Oil switches for highpotential currents are constructed, as shown in the Figure, with the terminals and insulators mounted on the cover of the oil-pot b, and the operating and tripping mechanism mounted at the side, a single lever a projecting through the side wall of the cover and engaging with the tube o carrying the movable contact-bar d. The short outer arm of the lever a is connected to a link f, which forms a toggle combination with a lever g adapted to be operated by a solenoid i in order to close the switch. The toggle, overset in the closed position, is tripped by a solenoid k to open the switch. Both operations may be effected by hand. A number of levers, such as a, may be mounted on the same shaft in a double or triple pole switch.
