A Spring Spade Terminal features a spring mechanism for tool-less connection, a pre-insulated barrel section for inserting a wire, and a flat, forked tongue on the opposite end. The tongue is made to slide onto a compatible screw terminal, and the spring provides constant pressure for a secure connection.Attributes:• For use with Wire of size 12-10 AWG• For use with a Screw of size No. 10Applications:A Spring Spade Terminal creates a secure and reliable electrical connection between the end of a wire and a screw. This is achieved through the spring mechanism that applies constant pressure on the inserted wire, forming a tight grip without the need for crimping or soldering.
