What are the two primary purposes of the terminals on a switch or receptacle?

The focus of the terminals on a switch or receptacle primarily revolves around the connection and interaction with electrical wires. They serve as vital contact interfaces between the internal mechanisms of the switch or receptacle and the external building wire, ensuring reliable connections for electrical current.

In the case of bundling stranded wire, terminals provide a point where multiple strands can be securely connected, enhancing the stability and conductivity of the connection. This is crucial in achieving a safe and effective electrical operation, as loose or poorly connected wires can lead to arcing or other electrical issues.

Indeed, terminals play a crucial role in establishing a safe and efficient link for electric current, making them essential components in any electrical installation. The emphasis on the practical aspects of wiring and secure connections highlights why this answer effectively captures the primary purposes of terminals in the context of switches and receptacles.
