FIELD: electrical engineering, temperature switches meant for monitoring, regulation and limiting temperature. SUBSTANCE: temperature relay has case 1, mobile and immobile contacts 2, 3 located in it, temperature-sensitive element 7 of thermomagnetic material with definite Curie point, permanent magnet 9 put on restoring carrier 10 for movement relative to temperature-sensitive element 7 and kinematically coupled to mobile contact 2 and mobile temperature regulator 16. Relay is fitted with ferromagnetic element 19 mounted in case 1 for movement and interaction with one of poles of permanent magnet 9. Temperature-sensitive element 7 interacting with other pole of permanent magnet 9 is placed between permanent magnet 9 and mobile temperature regulator 16. The latter is made of ferromagnetic material and is positioned in groove 17 formed by wall 18 of case 1 and temperature-sensitive element 7. EFFECT: enhanced functional reliability and accuracy. 3 dwg
