The J1772-2010 Standard seems to require a switch in the "nozzle" as part of a "proper" Proximity circuit implementation.
Measure the Resistance of the nozzle's Proximity pin to the ground pin. It should be about 150 ohms normally, and about 480 (150 + 330) ohms while the "Release" lever is pressed.
The internal switch shorts across a 330 ohm resistor that is wired in series with a 150 ohm resistor.
