Abstract

See full text

A shape-memory alloy actuated switch (SMAAS) is provided that enables the stable switching of two separate circuits. The presently disclosed SMAAS includes a substrate, one or more electrical contacts attached to the substrate for connecting to load circuits, and one or more electrically conductive elements for selectively connecting the one or more electrical contacts. The disclosed SMAAS also includes one or more shape-memory alloy actuators attached to the substrate. The one or more shape-memory alloy actuators are configured to move the one or more electrically conductive elements. The shape-memory alloy actuators are self-heated by passing current through the shape-memory alloy material. The disclosed SMAAS may also include electrical contacts to connect an external control current to the shape-memory alloy material. In some examples, the provided SMAAS includes one or more retention mechanisms to prevent movement of the electrically conductive elements after actuation.
