Abstract
In an electromagnetic relay, a bridge contact arrangement whereby cooperating contact elements are disposed in one common plane lying next to one another. One of the cooperating contact elements angularly cantilevers over the free end of the other, shorter cooperating contact element with a cross-leg. In this manner the contact element can be provided with contact pieces aligned and properly spaced with one another. An armature-carried contact bridge spring serves to engage the contact pieces of the contact elements with equal contact pressure. The invention construction offers a simplified, reliable relay manufacture.
Claims6
An electromagnetic relay comprising a coil body carrier supported by an angular yoke having a first leg coupled to one pole end of a coil core and a second leg forming a bearing edge for a flat armature facing across a working gap with the other pole end of the coil core, a contact spring connected to said armature and extending longitudinally thereof, said contact spring having a transverse contact bridge portion outward from said armature for engaging at least one pair of cooperating contact pieces aligned with one another in one switch position, the improvement comprising at least one pair of contact elements in the form of side-by-side planar plates mounted in said carrier to extend together in a common plane, the first contact element free end having a cross-leg directed over the free end of the second contact element so as to extend across the linear axis of the second contact element, and the free ends of the first contact element cross-leg and the second contact element having said at least one pair of cooperating contact pieces respectively mounted thereon.
