Switching between automatic and manual modes is done with a selector switch. This device is designed to select one of several defined operating states (such as AUTO or MAN) and stay in that state until it’s moved to another position. It gives a clear, maintained indication of the current mode and is wired into the control logic so the machine runs automatically in AUTO or allows manual control in MAN, depending on the position.

Pushbuttons are typically used to start or stop actions or to jog in manual mode, not to set the overall operating mode. An emergency stop is a safety device meant to cut power immediately in a fault or danger, not to toggle modes. A key switch can control access or enablement, but the standard device used to switch modes is the selector switch, which provides a distinct, permanent mode selection that the control system can read.
