The CS-37 Failsafe 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.
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.
For less demanding applications consider using the CCS-37 Commercial
range.
