K4 Series-SPDT Electro-Mechanical Switch - Internal Termination

Rf Electromechanical Switches

MCLI's electromechanical switches are high quality, intricately built switches that are used to route signal through different transmission paths. Our electromechanical switches are extensively used in various broad range systems from simple test bench applications to intricate switch matrixes systems. We have ranges up to 26 GHz and offer multiport solutions up to SP6T (single pole six throw). If you are lookings for a multitude of options, we can spec different mechanical and connectorized packages to meet your needs.
