Abstract
A force transducer having a post connected to an underlying substrate having a plurality of strain gauges, is protected from otherwise damaging static electric discharge current using a grounding guard. The guard is preferably a flat conductive member having an aperture for receiving the post and a tab for connection to electrical ground. The guard surrounds the post and overlays the substrate to channel such current away from delicate strain gauges and other electronics. In the preferred embodiment the aperture is formed by bending up a plurality of flaps cut into the guard and bent up to receive the post in press-fit engagement.
