The EV-Switch tm / TFI-204 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. 

The User moves the [Japanese-technology, heavy-duty] switch to select either the Dr(yer) or EV port.  AC connection is determined by the switch.
When the switch is on Dr side, the (left) LED is turned on and Dr side receptacle gets AC connection. (EV side is completely OFF).
When the switch is on EV side, the AC meter is turned on and EV side receptacle gets AC connection. (Dr side is completely OFF).

The EV-Switch tm / TFI-204 comes with two generic NEMA 14-30R receptacles and an AC multi-meter (Japanese technology, measurements are within 1% accuracy) and can operate at 24A up to 45C (113F) ambient temperature.

The option -B comes with two Bryant industrial-grade NEMA 14-30R receptacles.

The option -H comes with two Hubbell industrial-grade NEMA 14-30R receptacles.

Buyer 's Tip :

This product is for a user, with only one electric vehicle to charge at 24A and a (after-1996) NEMA 4-prong 14-30R outlet, who wants the additional convenience and safety enhancement of a Japanese-technology AC meter. Note that :

Operating Temperature Range :   0 C to 45 C (32 F to 113 F)

Note: Option -H (Hubbell 14-30R receptacles) may currently require long lead time due to limited availability !
