Operating characteristics and safety features of slipon units will be demonstrated by an exhibit of Westinghouse Electric in connection with the N.E.L.A. convention in Atlantic City, June 5-10.
Actual short circuits will be interrupted and other performance features will illustrate the efficiency of the device in the control of domestic light and power circuits.
Martha Leech suggests the simplicity with which a flipon is operated.
