The opposite is true: C on an HOA switch indicates that the contacts are closed, while O indicates that they are open. A C on an HOA switch stands for Hand-Off-Auto switch, which is used to control the operation of a motor. The C stands for "Controlled" mode, which means the motor is controlled by the switch.
