Abstract
In a measuring instrument of the kind in which an axial movement of an input member is required to be converted into a rotary movement of an indicating member, such as a pointer movable across a scale, the input member acts against a cantilever mounted spring. The indicating member is pivotably mounted adjacent the free end of the spring for angular motion in a plane substantially perpendicular to the plane of deflection of the spring by the input member. Co-operating means, respectively on the indicating member and the free end of the spring, are magnetically attracted into contact with each other for converting motion of the spring into motion of the indicating member and preferably these co-operating means are a cam or ramp of part helical configuration on the spring and a follower on the indicator, one or other of the cam or the follower being a magnet.
