There are many benefits to using the latest Altech CX-Series of spring clamp terminal blocks, the most important being the time it takes for installation. With the use of a tool or narrow screwdriver, push into an insertion space to open a pre-loaded stainless steel spring. Your wire can then be inserted into an opening in the spring leg. By removing the tool, there is a spring force that presses the conductor against a copper tin plated current bar for a highly reliable connection.

These terminal blocks are used with solid or stranded wire and create a very secure connection — unlike screws which can loosen over time or in high-vibration applications. Spring clamp terminal blocks are often designed into vehicles because of their natural resistance to vibration and shock. Under the high-vibration movement of vehicles and aircraft, the spring clamp terminal block maintains a secure hold on the wire long after when a screw type terminal block would have loosened and caused a potential failure.

With the addition of Universal Push-In Jumpers this is a superior terminal block series.
