Abstract
Temperature monitoring device for monitoring or controlling the temperature of an object, and preferably indicating and/or recording abnormal temperature variations of the object includes a housing having a contact portion for contacting the object, a sensing member in heat transferring contact with the contact portion for emitting signals representative of the object temperature, a control device that receives signals from the sensing member and actuates an indicator, a power source connectable to the sensing member, the control device and the indicator, and a switch biased to interrupt the power supply to the sensing member, control device and indicator. A portion of the housing is movable between a first position where the switch interrupts the power supply and a second position in which the housing portion urges the switch to the power supply position.
