Tower Piezo Switch Development - G23NNYA-42408 - Switch, Piezo.

A piezo switch is an electrical switch based on the Piezoelectric Effect. 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". When the FET is on, current can flow through it as with a conventional metal contact-based switch. After the voltage pulse is dissipated in the gate resistor, the FET turns back "off", its normal high impedance state. The Piezoelectric Effect uses the fact that force applied to certain materials causes stresses that generate this electric charge. In the case of piezo switches, the force could be compressive pressure that causes the (typically disc-shaped) piezo element to bend very slightly like a drumhead.

contactors provide the switching (on/off) function.

Note: Designed with a low drop out voltage making them ideal for air conditioning, heating and refrigeration applications. Space saving dimensions allow for smaller panels and more wiring room. The combination of multiple mounting holes and slots allows these contactors to be fastened onto panels and provide interchangeable mounting with many competitive contactors.

Siemens starters and contactors includes replacement products for parts formerly produced by Furnas Electric, including Furnas contactors and motor starters.
