Internal Mechanical Interlocks Prevents the opposite contacts from transferring when either one of the coils is energized and the respective contacts are closed. Reversing Operation losing either external start/stop switch at or will cause the motor to turn in either direction. Dynamic raking Operation Internal switch provides for dynamic braking current flow through the motor shunt-fields series (SF) and. Switch S is mechanically closed when either coil is energized and maintains that position until the alternate coil is energized.
