Claim 20:
21. A method comprising:
a) responsive at least in part to movement of a trigger on a handle of a body of a defibrillator, causing a hammer that is movably mounted relative to the body to impart an impact strike to a piezoelectric crystal of a circuit within the handle,
wherein the circuit is in operative connection with a pair of disposed externally accessible electrodes that are in fixed operative connection with the body,

b) closing at least one force actuated electrical switch in operative connection with the circuit responsive at least in part to a pressing force of the pair of electrodes against a surface, wherein closing the at least one electrical switch operatively electrically connects at least one of the pair of electrodes and the piezoelectric crystal,
c) subsequent to (b) and responsive at least in part to the impact strike, causing an electrical potential between the pair of electrodes,
wherein the electrical potential between the electrodes is sufficient to provide an electrical shock to heart muscles of a patient through the pair of electrodes when the electrodes are in direct engagement with the chest of the patient.
