By pressing, a piezoceramic generates a voltage pulse. The power of the voltage pulse is amplified from the integrated electronic circuit to a bipolar switching output. During the voltage pulse the electronic is switching for the specified pulse duration. The The switching time of the electronic switching output depends on the actuation force and the operation speed. Connection diagram of a single switch NO (Normally Closed): In the unactuated condition, the piezo ceramic is in a high-impedance state and the switch has an output resistance greater than 10 MOhms. If the piezo-ceramic is actuated, the output resistance is reduced to a value smaller than 20 ohms. This corresponds largely to the functionality of a conventional mechanical switch.
