ABSTRACT:
A resettable heat actuated link having an associated releasable member comprises first and second gripping portions for acting cooperatively to engage the releasable member in a normal position and to release the releasable member in an activated position. Along with the first and second gripping portions there is provided a heat responsive bimetallic element for causing the gripping portions to move to the normal position in response to ambient temperature and to cause the first and second gripping portions to move away from each other to an activated position in response to a preselected increase above the ambient temperature and to release the releasable member at the increased temperature. The first and second gripping portions, the heat responsive bimetallic element, and a base for mounting the link are integrally formed from a single bimetallic strip.
