NEW SNAP SWITCH.
Pass & Seymour, Inc., of Solvay, N. Y., have recently placed on the market the new snap switch shown by Fig. 4, which they say is the result of two years' study and experiment. In consideration of the rough usage and frequent service usually sustained by a switch of this kind, it has been carefully designed and submitted to tests throughout the entire period of development; the weak points being remedied as fast as they appeared. The tests of the switch have been quite severe, they having been subjected to 50,000 makes and breaks at the rate of three per minute, while carrying 15 amperes at 220 volts. As the underwriter requirements do not permit more than 660 watts to be controlled by a single-pole switch, the switches are marked 3 amperes, 220 volts; 6 amperes, 110 volts; but they are warranted to carry from 10 to 15 amperes without heating. The switch is at present only made in the single-pole form, but a line of double-pole switches is in process of manufacture.
