Abstract
230,748. Cox, F. B. Dec. 21, 1923. Regulating switches; contacts.-The fixed contacts of electric switches are formed as single blades, the co-operating movable contacts, consisting of two - part springs bearing contact portions adapted to engage the opposite sides of the fixed contacts. As applied to the switch described in Specification 230,566, the fixed contacts K, Figs. 5 and 6, are formed of U-shaped copper strips bent over blades k<1> of phosphor-bronze which are held in recesses m<5> of adjustable contact carriers M supported on insulating bars J. The movable contacts, Figs. 3 and 4, consist of copper jaws P attached to blades 0 of phosphor bronze which are clamped in carriers clamped in the rotatable insulated switch shaft A<1>. The securing screws q<7> may be surrounded by a tapered sleeve q<6>, Fig. 7, engaging corresponding recesses in the holder Q and blades O. In a further modification reinforcing springs O<1> may be provided as shown in Fig. 15 and flexible connections O<3> between the blades P and holder Q as shown in Fig. 16. In Fig. 17 the fixed contact K<1> is of wedgeshape. The Specification describes the application of such contacts to the faceplate and drum type of regulating switches. Specification 231,227 also is referred to.
