Abstract The present invention relates to preparation of a kind of waxy temperature sensitive medium for temperature control switch. The said temperature switch is used in automobile engine for temperature control in 40-70 deg.c temperature range and has one obvious flat part of temperature characteristic in 50-60 deg.c temperature range. One of the temperature switch may be used to replace two available temperature control switches. During the production of the medium, some commercial petroleum wax is selected as material and this reduce its production cost greatly.
