control circuit are similar to the rungs of a ladder. Author’s Comment: An important point to remember is that schematics show motors and control equipment in the resting, or off state (sometimes called the “shelf” state). Part of the difficulty, when first learning about motor con-trols, is in understanding how the different components of
