CHANGING THE STATE OF A SWITCH THROUGH THE APPLICATION OF POWER

摘要

A switch includes a spring. The switch further includes a collapsing element. The spring has a first spring state in which it is being held in tension by a restraining element and a second spring 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 have a first 1-2 electrical connection state when the spring is in the first spring state. The first contact and the second contact have a second 1-2 electrical connection state different from the first 1-2 electrical connection state when the spring is in the second spring state.
