The armature 8 of channel section is pivoted at its lower ends and drawn away from the enlarged end 2 of the core by a spring 12. The unit is mounted on a plate 13 by means of a nut 16 and is kept from rotary displacement by a pair of tongues 6 projecting from the yoke into holes in the plate. To facilitate the photographing of the counter readings the numerals may be white to contrast with the wheels and cover.
