Abstract
A switch includes a spring. The switch further includes a collapsing element. The spring has a first state in which it is being held in tension by a restraining element and a second state in which it is not being held in tension because the restraining element has failed. The collapsing element is situated such that when sufficient power is applied to the collapsing element heat from the collapsing element will cause the restraining element to fail. The switch further includes a first contact coupled to the spring. The switch further includes a second contact coupled to the spring. The first contact and the second contact are separate from each other when the spring is in the first state. The first contact and the second contact are electrically connected to each other when the spring is in the second state.
