Additional Details:

The PVA3352 typically requires a low DC control voltage and current to activate the switch. It uses an LED to transmit the control signal optically to a photovoltaic generator, which in turn drives MOSFETs to switch the load. This design ensures excellent isolation and minimizes noise coupling. The specific voltage and current ratings for the PVA3352 will vary based on the exact configuration; datasheets should always be consulted for accurate specs. Its solid-state nature makes it less susceptible to vibration and shock compared to electromechanical relays.
