Limit switch for critical temperature
Operate alarms or shutdown equipment
SPDT snap-acting switch
Fits most engine applications

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. Applications include:

Engine coolant
Compressors
Engine lubrication
Mobile equipment
Generators
Irrigation systems
Oil field systems
Construction equipment
Marine engines
Electric motors
