Abstract
An electromagnetic actuator in one embodiment includes characteristics of very fast actuation, shock invariant design, and compact size. The actuator may be controlled via a small low voltage power source such as a battery and simple switching logic. Such characteristics are ideally suited for incorporating the actuator into the firing mechanism of a firearm, which are subjected to drop tests to confirm the firearm will not discharge in the absence of trigger pull. Very fast snap-like action is attained by balancing the magnetic forces of two opposing permanent magnets around a stationary yoke and rotating member to create three circulating magnetic flux circuits. A central electromagnet coil on the yoke amplifies the magnetic flux of one side of the rotating member or the other depending on the power source actuation polarity, thereby creating two possible snap-like actuation positions. The actuator is usable in firing mechanism release or blocking applications.
