<p>The flat plug-in lock for safety disconnecting switch without longitudinally movable locking insert has a horizontal main lever which is moved in left-hand swivelling direction across the lock inside by its own gravity and that of an intermediate lever above the same, or by a spring urging both levers. Its right hand swivel movement is imparted via the key recess rim with correspondingly oblique location. The lock has preferably a locking lever moved by the key tip, actuated in opposite swivelling direction by another spring, either directly or via a reversing lever. In the locked position the main lever may be blocked by the locking lever and vice versa.</p> |
