Abstract
An improved force transducer which may, for example, be used as a joystick control for computer display control. Co-planar strain gauges are configured for response to forces applied in each of three orthogonal directions. A post and underlying ceramic substrate, the latter having the strain gauges mounted thereon, are mounted to a printed circuit board by means of a conductive epoxy or solder in a gap between the substrate and the circuit board. A retainer may be used to limit the extent of post displacement in X and Y directions to prevent damage to the assembly from forces which would otherwise exceed the physical limits thereof.
