Commercial CCS-37. Miniature Transfer DC-18GHz Latching. The CCS-37 Latching Switch is a long-life high performance transfer switch designed for use in 50 Ohms coaxial transmission lines operating over frequencies ranging from DC to 18 GHz. The switch is designed for minimum size compatible with SMA connector spacing. This switch is provided with a magnetic latching actuator which is particularly desirable in applications where actuator power consumption must be kept to an absolute minimum. The latching type actuator requires less switching current than the failsafe type. In the self-cutoff version, power is applied only for the very short duration (approximately 50 msec. max.) of the actuator transfer from one position of the other. This makes this type of actuator especially suitable for portable battery operated systems. This version of the CCS-37 has a latching actuator (12 VDC with both indicator contacts and self-cutoff), female SMA connectors (4) and includes Option T: TTL Drivers with Diodes.
