Abstract: An actuator movable in a plane parallel to coordinate x and y axes is biased to a normal position by a leaf spring parallel to the x axis and flexible in the y directions. A lever parallel to the y axis has the actuator at one end, a rigid connection to the middle of the leaf spring at the other. The lever is constrained to lengthwise motion and to swinging about said connection. The leaf spring ends are confined to x direction motions. Strain sensors, secured to the leaf spring between its middle and its ends, are connected in bridge circuits that produce outputs respectively corresponding to x and y components of actuator displacement.
