Terminals connect conductors to an external circuit using a wide variety of methods. Alligator clips are a common type of temporary terminal and feature a spring-loaded design for quick attachment and removal without additional tools. Fork and spade terminals provide conductivity using a screw. The metal connector, known as the fork or spade, fastens underneath the screw. Ring terminals work similarly but feature a closed loop instead of a fork or spade. Pin terminals are ideal for temporary connections via setscrews or clamps and are compatible with pin-type terminal blocks.
