O2 Flows w/Switch Off

Yesterday while doing some testing (just up to FL 200 but enough to need to use the O2 system) on my 1967 T337B, I noticed that the oxygen flows when the masks are plugged in even if the O2 system lever is in the "Off" position. Is this normal? Or does it indicate that the lever isn't working? Or ???
