Relay armature mounting

A relay, comprising a core with a coil having an axis;

• and an armature including a stationary armature element having a first arm portion arranged to be fixedly connected to a core with a coil at one axial side of the latter, and a second arm portion extending substantially normal to said first arm portion, a movable armature element extending at the other axial side of said core with said coil and movable relative to said stationary armature element, and means forming a joint between said movable armature element and said stationary armature element, said joint forming means including a substantially trapeze-like projection formed on said second arm portion of said stationary armature element and having a predetermined cross section, and a groove formed in said movable armature element and having a cross section which is somewhat greater than the cross section of said trapeze-like projection, said cross section of said projection of said second arm portion of said stationary armature element having two inclined flanks forming a predetermined angle therebetween, said cross section of said groove of said movable armature element having two further inclined flanks defining therebetween a further angle which is somewhat greater than the angle between said flanks of said projection, said cross section of said projection of said second arm portion of said stationary armature having a circular end section connecting said inclined flanks with one another, said armature elements being arranged so that said projection and said groove cooperate with one another and thereby said movable armature element can perform a rocking movement relative to said stationary armature element.
