What component in motor control systems can offer both start and stop functionality?

The component that offers both start and stop functionality is a manual starter. A manual starter is designed to control the operation of a motor by allowing the operator to start or stop the motor through a physical switch or lever. When the operator activates the manual starter, it closes the circuit, allowing current to flow and starting the motor. Conversely, when the operator deactivates the starter, the circuit opens, stopping the motor.

This manual control capability makes it a fundamental element in motor control systems, particularly in applications where an operator needs direct control over the motor's operation. Unlike other components, such as relays or overload relays, which typically serve more specific functions within the system—such as protection or control of multiple circuits—the manual starter combines both the start and stop functionalities into one unit, providing an efficient means of directly managing motor operation.
