TEMPERATURE CONTROL DEVICE Russian patent published in 2002 - IPC

FIELD: measuring technique, possibly instrument making, for example switch type temperature pickups for refrigeration and firing technique. SUBSTANCE: switching lever is continuously forced by means of arm of microswitch; said arm is jammed between body and contact spring of microswitch. Elastic lug of said spring rests upon body and provides springy effort acting from arm of microswitch to side of switching set of contacts. Free axial motion of arm of microswitch is more than axial motion of microswitch contact spring realized by spring in point of its contact with arm of microswitch from time moment of starting its motion until time moment of operation of microswitch by value of possible movement of switching lever after operation of microswitch. EFFECT: enhanced stability of operational parameters, increased useful life period. 1 dwg
