Spring clamp terminals provide a quick and reliable connection. Spring clamp terminals are perfect for applications with high vibration, or wide temperature fluctuations as the spring maintains a constant force on each wire. Changes in wire diameter because of use, or temperature change are accommodated by the spring, maintaining constant pressure on the wire, holding it firmly in place. Spring clamp terminals also provide a gas tight connection between the terminal and wire. This means that corrosion is minimized and reliability is increased. Spring clamp terminals are an approved method by both IEC and UL, and provide consistent contact pressure.
