摘要： The purpose of the invention is to improve reactiveness of a thermomagnetic actuator in a security electric switch, so that the time delay prior to interruption of the electric circuit through the switch due to electric overloading could be essentially reduced. The invention provides that a yoke (6) is along its complete circumference spaced apart from the internal surface of a casing (1) and is surrounded with an thermal insulating ring (10), which is uninterrupted along its complete circumference and is on the one hand rest on the internal surface of said casing (1) and on the other hand on said yoke (6). An anchor (2) is, at least on its side which is faced towards the closed end portion (1 ") of said casing (1), furnished with a centrally arranged throughout axial passage (2'), and on its opposite side, which is faced towards said yoke (6), with a centrally arranged cavity (2"), wherein said passage (2') within the anchor (2) is adapted to receive a thermal insulating guide (9), which is inserted between the anchor (2) and the casing (1), while said cavity (2") is adapted to receive a portion of said spring (3), which is faced towards the anchor (2), but not also that portion of the spring (3), which is faced towards the yoke (6). Moreover, a thermal insulating bush (11) is inserted between a bimetallic disc (7) and an actuating needle (5).

摘要： The purpose of the invention is to improve a security electric switch by increasing its reliability and also by simplification thereof. The switch according to the invention said switch assembly (2) consists of an immovable contact member (21), which is made of an electric conductive material and is electrically connected with said coil (31) of the interrupting assembly (3), which coil is electrically connected with said first contacting terminal (13) on the casing (1) of the switch, by which said immovable contact member is arranged within said casing (1) outside of said interrupting assembly (3) and on that side thereof, which is faced towards said seat (11), as well as of a movable contact member (22), which is also made of an electric conductive material and is inside of said casing (1) of the switch arranged adjacent to said immovable contact member (21) and is electrically connected with the other connecting terminal (14) on the casing (1) of the switch, wherein said movable contact member (22) is pivotally embedded within a cradle (220), which is formed on a free end portion of a cantilever beam (221) in the area in front of said needle (32) of said interrupting assembly (3) and is mechanically and electrically connected with said second connecting terminal (14), so that said movable contact member (22), which is embedded in said cradle (220), is pressed towards said immovable contact member (21 ) by means of a spring (222), by which it is supported in the adjacency of said cradle (220), but can be also moved in the opposite direction i.e. away from said immovable contact member (21) and against the force of said spring (222) when said switch member (4) is pivoted due to impact of the needle (32).

摘要： The purpose of the invention is to create a switch, which should be suitable for integration into each disposable electric circuit, upon which it should on the one hand enable protection of the circuit against electric overloads, and on the other hand also measuring of energy or power consumption of each load integrated within said circuit. To this aim, a device is proposed, in which an induction unit (11) of an actuating mechanism (1) is integrated within a phase conductor (L) and is moreover adapted to cooperate with a thermal interrupter (12) and a triggering needle (13) suitable for actuating a switch (S), and in addition to a primary coil (112) also comprises a secondary coil (115), which is suitable for detecting each current intensity within said phase conductor (L) and is arranged adjacent to said primary coil (1 12) and electrically connected with a neutral conductor (N), wherein said device also comprises an electric power consumption meter, which is electrically connected to the second coil (1 15) and jointly therewith also to the neutral conductor (N).
