10.3 Choosing the Right Mechanism

Because of differences in the amount of force, the required electric power, and the size and weight of the different release mechanisms, the process of selecting the right mechanism is not simple. In Fig. 10.11, some qualitative guidelines are offered to aid the selection process.

Fig. 10.11Properties of retention-release mechanisms

The large electric power needed to operate some of the release mechanisms suggests that those mechanisms that need to be deployed simultaneously be staggered, if possible. In addition, since some of the devices require large currents (at low voltage), several may be connected in series rather than in parallel.
