Abstract
A piezoelectric fuze, especially for projectiles, having a piezoelectric element which converts the mechanical shockwave produced upon impact on a target into an output signal for igniting a detonator. A control circuit is provided for generating an output signal and a threshold switching circuit is provided for receiving the outputs of the control circuit and the piezoelectric element as a superimposed signal for establishing a connection between a power source and a detonator of the fuze when the threshold value of the threshold circuit is exceeded.
