Abstract
A construction for actuator assemblies is disclosed using a material of low permeance as a structural element, included normal to the axis of coil movement to lower coil inductance by reducing reactance flux in support structures and providing a channel for eddy currents set up in response to coil reactance. The net result is enhanced coil responsiveness to energization.
