By using very large-scale integration (VLSI) manufacturing processing techniques, an extremely small thermally actuated switch is constructed. Switches thus manufactured may be single throw (ST), normally closed current carriers that open with a current surge to provide circuit protection. Double throw (DT) switches may be constructed to re-route current flow at an upper current limit or upper chip temperature limit. Normally open switches may be constructed for chip temperature detection or used as current shunts actuated by chip temperature.
