Abstract

511,092. Electromagnetic relays. VIGREN, S. D., and SVENSSON, R. A. June 13, 1938, No. 17505. [Class 38 (v)] In an electromagnetic switch having a number of movable contact springs, these are actuated by a common operating member 23 in the form of a comb, which is itself operated by the armature. The top and bottom ends of the member 23 fit respectively into holes in a pre-tensioned spring 26 and a stiff metal bridge 16, and the bridge 16 is adjustable in a vertical direction by a screw 17 so as to vary the initial position of the member 23. The member 23 passes through holes in both the fixed and movable contact springs, but the holes in the latter are smaller so that the teeth of the comb engage them. The fixed contact springs have side lugs adapted to engage slots in a support 18. A fixed contact spring such as 6, Fig. 3, may have its end bend up as shown. This will serve to raise also the movable contact 11 so that the member 23 will have to move a greater distance before it engages it. Thus 11 may be called a "latebreak " contact. Fig. 3 shows the following contact combinations as examples of what can be obtained:-a " make " contact 10, 14, a " make and break contact 9. 13, 8, an "early break " contact 12, 7 and a " late-break " contact 11, 6. The contact springs are preferably of the pretensioned kind described in Specification 473,305.
