ABSTRACT:
An electromagnetic relay includes an armature 1 supported in a central longitudinal bore 12 of a one-part bobbin 2 by means of a bearing which includes a first pair of curved bearing surfaces 1a, 1b, formed on the armature 1 and engaging a second pair of supplementarily curved bearing surfaces 2a, 2b, formed in the bore walls. The first bearing surfaces 1a, 1b may be either cylindrical in which case cylindrical second bearing surfaces 2a, 2b are formed in ribs 2c, 2d projecting inwardly from opposite bore walls, or spherical in which case spherical second bearing surfaces are formed directly in opposite bobbin walls.
