| 摘要 | An electro-magnetic relay arrangement in which a pair of spaced electromagnets are supported on a base and a pair of associated armatures are pivoted relative to the electro-magnets about aligned axes. A rigid wire connects the two armatures to extend parallel to the axes and a pair of springs biasses the armatures away from the electro-magnets, said pair of springs extending between the base and portions of the rigid wire adjacent the respective armatures. | ||||||
| 权利要求 | 1. An electro-magnetic relay arrangement comprising a support, a pair of electro-magnets mounted on the support, a pair of armatures each mounted for pivotal movement about an axis towards and away from one of the electromagnets, said axes being substantially aligned, and means for biassing said armatures away from the respective electro-magnets, said biassing means comprising a member engaging said armatures and extending therebetween substantially parallel to said pivotal axes and a pair of springs in spaced relationship extending transversely of said member and engaging said member and said support. 2. An arrangement as claimed in claim 1, wherein the member engaging said armatures is a substantially rigid wire. 3. An arrangement as claimed in claim 2, wherein the wire is provided with a crimped portion adjacent each armature, each said crimped portion providing a plurality of locations for engagement of the respective spring. 4. An arrangement as claimed in claim 2, wherein the wire is provided with turned ends which engage in apertures in the respective armatures and is pivotable relative thereto. 5. An arrangement as claimed in claim 4, wherein the apertures are provided in extensions of the armatures beyond the axes. |
