The CCS-47/CS-47, a durable high performance transfer switch is meant for 50 Ohms coaxial transmission lines who operating frequencies range from DC to 12 GHz. The switch is devised to be used in minimum spaces, hence compatible with Type N or TNC connector spacing. These are not only fail safe switches, but they have spring-operated actuator which makes it perfect for applications in which the switch remains connected to a single position. It would be normally closed and used only for periodical switching. When the switch is operating in the alternate position, it means holding power is required and used only in such applications. The circuit is also quite simple, because there is only one DC circuit. CCS-47/CS-47 is noted for its durability and excellent performance. It functions as a crossover switch designed for 50 Ohms coaxial transmission lines.
