Not sure your assessment is correct.





Though I've never had this fuel cock in hand, on the 2 pictures here above I think the cock in OFF position.


For clarification, I'll name the left part of the fuel cock the "Hammer Head" (the little cylinder in dark red colour on Oleg's screen), and the hollow right hand side, the "Handle" (in dark grey).

So from the OFF position shown on those pictures if you rotate the cock clockwise you do not need to press the catch to open the fuel valve to MAIN TANKS ON or RESERVE ON positions.
The "Hammer Head" can easily move.

If you rotate the cock anticlockwise from one of these later positions, you definitely need to press the metal catch to be able to slide the "Hammer Head" to the OFF position.
This catch should avoid to shut the fuel off in flight inadvertently.
