Flexitest Case
The type FT (Flexitest)(i) case is a dustproof
enclosure combining relay units and knife
blade test switches in the same case. This
combination provides a compact flexible as
sembly easy to maintain, inspect, test and
adjust. There are three main units of the
type FT case: the case, cover, and chassis.
The case is an all-steel welded housing con
taining the hinge half of the knife-blade test
switches and the terminals for external con-
nections. The cover is a molded phenolic
frame with a clear glass window, a thumb
nut, and a hinge. The hinge fits over the top
flange of the case. The thumb nut, which
fastens to a stud on the bottom flange of the
case, holds the cover securely in place on
the case. The chassis is a steel frame that
supports the relay elements and the contact
jaw half of the test switches. This slides in
and out of the case. The electrical con
nections between the base and chassis are
completed through the closed knife-blades.
The case designation is type FT-32.
REMOVING CHASSIS
To remove the chassis, first remove the
cover by unscrewing the captive thumb nut at
the bottom and lifting the cover hinge off the
top flange of the case. This exposes the re
lay units and all the test switches for inspec
tion and testing. The next step is to open the
test switches. In opening the test switches,
they should be moved all the way back against
the stops. With all the switches fully opened,
release the cam action latches and pull the
chassis outward. One cam latch is located
at the upper right and must be pulled down
ward for release. The other cam latch is
located at the lower left of the chassis and
must be pushed upward for release. The
chassis can be set on a test bench for easy
inspection, maintenance and test.
After removing the chassis a duplicate
chassis may be inserted in the case or the
blade portion of the switches can be closed
and the cover put in place without the chassis.
