Po izumu je predvideno, da je jedro (6) po svojem celotnem obodu odmaknjeno od notranje površine ohišja (1) in opremljeno s po njegovem celotnem obodu sklenjenim termoizolacijskim obročem (10), ki po eni strani nalega na notranji površini ohišja (1) in po drugi strani najedru (6). Po drugi strani je kotva (2) vsaj na svojem proti zaprtemu koncu (1") ohišja (1) obrnjeni strani opremljena z osrednje razporejeno aksialno luknjo (2'), na proti jedru (6) obrnjeni strani pa s prav tako osrednje razporejeno vdolbino (2"), pri čemer je omenjena luknja (2') v kotvi (2) prirejena za prejem termoizolacijskega vodila (9), ki je vstavljeno med kotvo (2) in ohišjem (1) ter prirejeno za vodenje kotve (2) med premikanjem sem ter tja vzdolž ohišja (1), medtem ko je omenjenavdolbina (2") prirejena za prejem proti kotvi (2) obrnjenega dela vzmeti (3) z izjemo njenega proti jedru obrnjenega dela. Razen tega je med bimetalnim diskom (7) in udarno iglo (5) vstavljena termoizolacijska puša (11).The purpose of the invention is to design a more responsive thermal-magnetic trigger of a safety electrical switch, so that the time delay of the interruption through the switch of the ongoing electrical circuit in the event of its overload is significantly reduced. According to the invention, it is provided that the core (6) is spaced from the inner surface of the housing (1) along its entire circumference and equipped with a thermal insulation ring (10) closed along its entire circumference, which rests on the inner surface of the housing (1) and on the other hand sail (6). On the other hand, the anchor (2) is provided with a centrally arranged axial hole (2 ') at least on its opposite end (1 ") of the housing (1) on the facing side, and on an equally centrally arranged recess on the opposite side of the core (6). (2 "), said hole (2 ') in the armature (2) being adapted to receive a thermal insulation guide (9) inserted between the armature (2) and the housing (1) and adapted to guide the armature (2) between moving back and forth along the housing (1) while said recess (2 ") is adapted to receive the spring-facing part (3) facing the armature (2) with the exception of its core-facing part.
