Push-in wire connectors, also known as push-in terminals or push-in wire nuts, are electrical connectors designed to simplify and speed up connecting wires. Electricians and installers can simply insert the stripped ends of the wires into the connector, and the connection is made - no twisting or screwing is required. This is especially handy in tight spaces where maneuvering with traditional wire connectors might be challenging and during temporary installations that may need to be taken apart later.
