The relay disclosed has a leaf spring (9) which acts as a contact spring and armature-reset spring and which has two arms disposed approximately at right angles to each other. The end of the first arm is suspended from a pin (6c) on the return pole piece (6) so that it can turn freely about the point of suspension. In addition, the cross-section of this first arm is reduced so that it is mainly loaded in tension, the armature reset force being provided substantially by the second arm (9b) of the spring. By means of a support element located between the return pole piece (6) and the first arm (9a) of the spring, the latter is biased slightly outwards, however, so that it exerts a small directive force on the armature (7) in order to draw the armature in predetermined fashion into its bearing. Owing to the difference in cross-section, however, this force has virtually no effect on armature resetting.
