Abstract: 257,862. General Electric Co., Ltd., Turner, H. C., and Sherwin, A. May 14, 1926. Electrically - released switches. - A reversecurrent cut-out, particularly for battery charging, has a movable contact M pivoted at M<3> on a bracket S secured to an armature F pivoted at G and controlled by an adjustable spring P. The contact itself is constrained in its movements by a strip spring M<1> secured to the bracket at V. In the open position of the cut-out, a face of the strip spring engages with a face of the movable contact on both sides of the pivot M<3> so that the contact is restrained against movement in either direction about its pivot. The cut-out is moved into the closed position by hand operation through the medium of the handle T and is held there by the electromagnet A<1>, A<2> having a central adjustable core C energized by a series winding D and a shunt winding E. In the closed position of the switch, as shown, the strip spring exerts only a slight pressure on the contact and this pressure is substantially the same even when the interengaging contacts become warm. The cut-out is set to act at a predetermined value of reverse current in the winding D by adjustment of the spring P and by adjustment of the air gap I. The gap is adjusted by rotating the core the end of which screws into the lower limb of the U- shaped core structure. The cores are maintained in a constant position in relation to the upper end of the central core by means of springs L<1>, L<2>.
