In a motor control circuit, which component typically holds the contacts energized once the start button is pressed?

In a motor control circuit, the component that typically holds the contacts energized once the start button is pressed is the holding contact circuit. This circuit works by maintaining the current flow to the relay or contactor coil even after the start button is released.

When the start button is pressed, it energizes the relay coil, which closes the contacts. The holding contacts, which are also part of the relay, create a parallel path that continues to supply power to the coil. This allows the motor to remain operational until a different action, such as pressing a stop button, interrupts the power supply.

Understanding the role of the holding contact circuit is crucial because it ensures that the motor control system remains functional without the need for sustained pressure on the start button, thereby enhancing user convenience and safety in operation.
