Are the old style swing plugs legal to use for new construction?

The kind of plug I'm referring to are the ones that the power is connected and disconnected to the line side of the branch circuit by the opening and closing of the door.

Swing jack, bus plugs are not compliant for new installs, because they are not capable of being operated from the floor. An older plant that still has these types, can continue to use them, on their old circuits.
368.17 (C) Feeder or Branch Circuits. Where a busway is used as a feeder, devices or plug-in connections for tapping off feeder or branch circuits from the busway shall contain the overcurrent devices required for the protection of the feeder or branch circuits. The plug-in device shall consist of an externally operable circuit breaker or an externally operable fusible switch. Where such devices are mounted out of reach and contain disconnecting means, suitable means such as ropes, chains, or sticks shall be provided for operating the disconnecting means from the floor.
