The control switching for a reversing starter can consist of ___.

The control switching for a reversing starter can indeed consist of either a stop push button (PB), a start push button and a forward/reverse selector switch, or a stop PB along with separate forward and reverse push buttons.

Using a stop push button is essential for safety, allowing users to halt the operation immediately. The start push button serves as an initiation point for the motor's operation, while the forward/reverse selector switch provides a simple means to choose the motor's direction either for forward or reverse operation. Having this selector switch can streamline the control process, making it straightforward for the operator to set the desired rotational direction with one control.

On the other hand, the configuration that includes separate forward and reverse push buttons offers a different approach. This method allows for an immediate change in direction while the motor is running by simply pressing the desired direction PB after stopping the motor with the stop button. This setup can provide quicker responses in applications where changing direction frequently is necessary.

Both configurations are valid for operations that involve reversing starters, thus making the option indicating that either arrangement can be correct appropriate, confirming that multiple designs can achieve the desired control functionality.
