DESCRIPTION

Commercial Failsafe TRANSFER, DC-18GHz

CS-37S

Elite Failsafe TRANSFER, DC-18GHz

The CCS-37S/CS-37S 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.

The failsafe switches on this page are provided with a spring operated actuator which is particularly

desirable in applications where the switch is connected to one position (normally closed) most of the

time and only periodically switched to the alternate position. In this type of application, holding power is

required only when operating in the alternate position. Also, switching circuitry is simplified, since only

one DC circuit is required.
