Mark VII switch interlock lock and motor mount
Posted: Wed Nov 07, 2012 4:02 am
The power switch is interlocked internally to prevent reversing direction without pressing the stop button. The key lock adds to that interlocking. The key must be in either the forward or reverse direction position in addition to the corresponding switch button being pushed. The lock also prevents any power switch depression when the key is removed. The lock has three positions - forward - off - reverse.
This shows the cam that is moved by the lock. The cam when moved away from the switch button(s) allows that button to be depressed.
The key interlock parts.
This shows the motor mount is different from the Mark 5/V in that one side is screwed to the front of the motor pan and the other side to the bottom of the pan.
