EV-Switch tm / TFI-20 Manual 240VAC Switch
The EV-Switch / TFI-20 is a Manual 240VAC Switch to time-share an existing 240VAC outlet between two AC loads. The user simply plugs the cable to the existing 240VAC outlet, then connects an AC load, e.g., an electric dryer to Dr side and another AC load, e.g., an EV charging unit to the EV side.
