ABSTRACT:
An actuated gauge pointer that includes a shape memory alloy element configured to move the gauge pointer when activated is provided. The actuated gauge pointer includes a first shape memory alloy element disposed within the perimeter of the gauge pointer housing. Additionally, the actuated gauge pointer may include a second shape memory alloy element to provide temperature compensation, and a bias member to return the gauge pointer to an initial condition.
