Abstract: Meter movement having a single U-shaped plate with an arcuate permanent magnet secured to one surface thereof. An inward extension of the plate forms one pivotal support for a moving coil and pointer assembly. The coil surrounds the magnet and the portion of the plate adjacent the magnet and is freely movable transversely of the magnet as the moving coil assembly rotates. The second pivotal support and the remainder of the magnetic circuit is provided by a second plate which is mounted in parallel spaced relationship to the first plate, the magnet being between the two plates. The second plate is spaced from the magnet to allow clearance for one leg of the coil.
