A piezo-electric trigger lever transmits a signal to a piezo-electric mechanism which releases the firing pin of a firearm. The signal from the trigger lever is passed through an electronic circuit or microprocessor which can process the signal before it is passed on to fire the firearm. The processing may include regulating the firing as a function of the pressure applied to the trigger; preventing operation unless the operator enters a predetermined code into the electronic logic circuit; and, in the case of an automatic firearm, regulate the number of shots fired per trigger pull. The operator may make in-the-field adjustments in these controls. The signal is transmitted from the logic circuit to a second piezo-electric device. This second device deflects to allow the release of the firing pin. Other pressure sensitive piezo-electric devices can be employed to act as safety mechanisms.
A firearm comprising a trigger member adapted to be displayed by a user, piezo-electric transducer means deformable by the trigger member upon displacement thereof for producing an electrical signal indicative of the pressure on the trigger member producing such displacement, firing means for firing the firearm in response to the electrical signal produced by the transducer means, processor means coupled to the transducer means and the firing means for receiving the electrical signal, comparing it to at least one signal indicative of at least one predetermined desired characteristic of the displacement of the trigger and producing an output signal to the firing means only when the displacement of the trigger by the user conforms to said characteristic.
