CS-37S
Commercial Failsafe TRANSFER, DC-18GHz
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.

All switches are marked with either a unique serial number
or a date code. Date codes are in accordance with MIL- Actuator Current vs Temperature

A failsafe switch reverts to the default or failsafe position
when actuating voltage is removed. This is realized by a
return spring within the drive mechanism. This type of switch
requires the continuous application of operating voltage to
select and hold any position. (Multi-position switches are
normally open with no voltage applied).
