Abstract
The inertial transducer comprises a foot, a modular key, at least one suspension means having at least three contact points, and heat dissipation means comprising multiple heat transfer points. The foot alternatively includes an opening or a cap. The cap may be frangible. Preferably, the foot includes a cylindrical wall that extends within the inertial transducer and the foot's lower surface is coplaner with the lower surface of a housing of the transducer, thereby reducing stack height. The cylindrical wall may or may not be threaded and may accept a shaft from a receiving apparatus used to associate the transducer with a substrate.
