Abstract

559,453. Electromagnetic and magnetic switches. CIANCHI, A. L. May 7; 1942, No. 6185. [Class 38 (v)] A movable contact such as 1x is carried by a flexible strip 5 to which is secured an armature 7, the strip flexing, when the armature is actuated, so that the armature pivots about its point of connection with the strip. In the form shown in Fig. 12 the armature is actuated by bodily movement of the magnet 8 upwards. In Fig. 14, the armature is moved one way or the other according to the direction of current in a coil 7<SP>1</SP>. a magnet 8 acting as a polarizing magnet. Specifications 501,815 and 552,185 are referred to.
