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

The two primary purposes of terminals on a switch or receptacle are to provide a point of contact for electrical connections and to facilitate the bundling of stranded wire. Terminals serve as the connection points for electrical wires, ensuring that the wires can securely connect to a circuit. This secure connection is crucial for effective power transfer and minimizing electrical resistance.

Additionally, terminals are designed to accommodate stranded wire, which is often used in electrical applications because of its flexibility and conductivity. Bundling these wires around the terminals enhances reliability and stability in the connection, allowing for safe and consistent operation of electrical systems.

Understanding the function of terminals helps ensure that electrical installations are performed safely and comply with established standards. The focus on contact points and the use of stranded wire demonstrates a fundamental aspect of electrical design, underscoring the importance of secure and effective connections in any electrical system.
