What is the difference between load contacts and auxiliary contacts?

Load contacts are designed to handle the main current that powers an electrical load, such as motors or lights, while auxiliary contacts are used for control purposes and typically handle lower currents. Load contacts are often found in devices like contactors and relays, directly switching the power to the load. In contrast, auxiliary contacts provide additional functionality, such as signaling or interlocking, without directly controlling the load. Essentially, load contacts manage power, while auxiliary contacts facilitate control and monitoring.
