Abstract: A plastic holder for a thermistor includes a base portion having opposite ends and a thermistor support surface. Endwalls extend outwardly from the support surface for receiving a thermistor therebetween. Outwardly extending abutments on the base portion adjacent its opposite ends inhibit displacement of the holder from a pocket on a spring clip. One of the endwalls has an oppositely extending extension wall with a recess in its outer end for receiving an electrical lead. A thermistor retainer projection extends outwardly from the base portion perpendicular to the support surface intermediate its opposite ends.
