electromagnetic compatibility except as noted.
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.

Installation Instructions
Mounting
1. The TSB can be mounted in horizontal or vertical angles (do not
mount the switch facing down).
2. Install the TSB switch in the engine water jacket location
recommended by the engine manufacturer.
3. Install the appropriate adapter nut into the engine water jacket. Use
thread sealant such as Teflon®tape as necessary.
4. Insert the sensing bulb through the adapter nut. The sensing bulb
must be fully immersed in coolant/liquid flow so liquid flows
across the sensing bulb.
5. Tighten the 5/8-18 UNF-2A compression nut to complete a liquid
tight seal.
Wiring
CAUTION:
DISCONNECT Electrical
Power before wiring.
1. See wiring schematic below.
Switch contacts are shown with no
temperature applied to the
TSB switch.
2. A spade (forked) terminal
is recommended for all TSB
switch connections.
3. Complete the wiring operation
making sure the voltage and current requirements are within the
TSB switch electrical rating.
