A thermal probe assembly has a unitary outer shell or housing forming an open end adapted to receive an electrical connector unit and having an inboard end defining a probe portion; the outer shell or housing has deformable wall portions forming a bore; a pair of terminals with electrical conductor portions connected to a thermistor have a plastics material mounting member premolded thereon; the plastics material mounting member is slidably fit in the bore to position the thermistor within the bore and to axially locate the thermistor in spaced relationship to the inboard end of the outer shell or housing; portions of the plastics material mounting member interlock with cooperating portions of the bore to operatively lock the thermistor in place within the outer shell or housing.

Temperature responsive probe apparatus

A thermal sensor assembly is shown as having first and second body sections with the first being a probe-like portion for introduction into a medium the temperature of which is to be monitored; first and second thermistors, electrically isolated from each other are situated within the probe-like portion; the first thermistor is in series with and between two terminals which are connectable to associated circuitry external of the sensor assembly; the second thermistor electrically connected to a third terminal is effective to complete a circuit to ground potential through the probe-like portion.

Thermal sensor assembly

An electrical switch assembly is shown as having a housing carrying three electrical terminals with first and second of such terminals respectively terminating in first and second fixed electrical contacts and the third of such terminals being electrically connected to a conductive spring; a further third fixed electrical contact, spaced from the first and second fixed contacts of the first and second terminals, has an aperture formed therein permitting the extension therethrough of an actuator which in turn carries a movable contact which is situated generally between the third fixed contact and the first and second fixed contacts with the spring engaging and urging the movable contact and actuator in a direction whereby the movable contact is moved toward the third fixed contact; a pressure responsive diaphragm situated generally at a side of the third fixed contact operatively engages the actuator and upon sensing sufficient pressure is effective to move the actuator and movable contact against the spring and towards the first and second fixed contacts of the first and second terminals.
