My evhub based adapter has a ridge that the charge handle clicks into. The ccs charge handle acts just like a j1772 handle, which immediately disconnects the pilot pin when the lever is pressed down, immediately stopping the charge process and disabling the high voltage conductors on the car side.
My modified adapter is, in fact, safer than the Setec, which has been criticized for ignoring that pilot signal from the station side and keeping the high voltage lines connected when pressed, which could result in an arc explosion if you unplug the ccs handle during charging.
