Description
The TSB switch is a direct mount switch for
temperature sensing. It has one limit contact
that can be used to activate an alarm, actuate
indicator lights or shut down equipment.
The construction of this instrument is the
same as our time-proven Swichgage
®
. A
precision machined brass mounting plate and
port captures a high quality stamped
beryllium copper diaphragm. The single-
pole, double-throw (SPDT) snap switch is
operated directly from the diaphragm, for
quick acting and positive switching. Trip
point is factory preset according to your
specifications.
Housing is weather sealed to prevent entry of
moisture, dust, etc. A glass-filled nylon
terminal block with quick-screw terminal
connections gives the TSB switch a real
advantage in industrial engine applications.
The TSB is ideal when reading is not
desired, but temperature is critical to
operational efficiency.
Intended for use in general purpose non-
classified areas.
