Piezo switch6/5/2023 ![]() ![]() ![]() After the voltage pulse is dissipated in the gate resistor, the FET turns back "off", its normal high impedance state. When the FET is on, current can flow through it as with a conventional metal contact-based switch. The charge generated by the piezoelectric element in the switch is typically used to turn on an integrated semiconductor device such as a field effect transistor (FET), causing the switch assembly's output to be active, or "on". Resiliently deformable potting means filling all open spaces which are located within the enclosure adjacent the circuit board means, the piezoelectric means and the actuating element, whereby the potting means prevents moisture intrusion into such spaces, and whereby the resilient deformability of the potting means enables deformational flow of the potting means sufficient to permit movement of the actuating element and the piezoelectric means.A piezo switch is an electrical switch based on the piezoelectric effect.
