Claim 13:
14. A method of monitoring tension in a strap apparatus, the method comprising:
attaching the strap apparatus to a structure, wherein the strap apparatus includes a load transmission device comprising:
an enclosure having a base portion;
first and second stops affixed to the base portion;
a first shaft extending through the base portion and through the first stop;
a second shaft extending through the base portion and through the second stop;
a plate positioned within the enclosure and coupled to the first and second shafts, the plate arranged to translate unidirectionally via translation of the first and second shafts through the base portion and through the first and second stops;
a unitary switch having an on state and an off state; and
a spring arranged to apply a spring force biasing the plate towards the unitary switch;

applying a tension force to the strap apparatus via a tensioning mechanism;
when the tension force is less than a threshold tension force:
retaining the unitary switch in the on state via the plate that translates via the first and second shafts; and
transmitting a first signal from the unitary switch in response to the tension force;
when the tension force is greater than, or equal to, the threshold tension force:
retaining the unitary switch in the off state via the plate that translates via the first and second shafts; and
transmitting a second signal from the unitary switch in response to the tension force.
