All tethers work via a simple principle. Two quick-links are restrained by pins pushed through a machined housing. A small BP charge is loaded into the housing chamber in the center, just .25G for the smaller units, .35G for the larger one. When fired the pins are pushed out and the quick-links are released. The Kevlar cord keeps the pin assembly and the housing attached to one of the quick links. The other quick-link is completely released.
