Abstract: In a moving-coil electrical instrument the electric coil is rotatably mounted on a spindle for angular displacement about the axis of the spindle. The ends of the spindle are located in respective bearings disposed in apertures of a frame and each bearing has a part that is angularly displaceable about the axis of the spindle between a first angular position in which the part supports the spindle and a second angular position in which that part is removable from the respective aperture. The coil is mounted on a support through which the spindle extends and carries a body to counter-balance the coil. The center of mass of this body is spaced from the plane which includes both the center of mass of the coil and the spindle axis. The support also carries a counterpoise body that is spaced from the counter-balance body about the spindle axis.
