Abstract: The present disclosure refers to a switch for interrupting of a circuit in which two voltage sources and at least one load are connected, wherein the switch actuate quickly in an emergency. The switch includes a main conductor connecting both electric voltage sources and said load, bridged by a supplemental conductor which is in parallel with the two voltage sources and the load, and prior to activation of the switch, interrupted and electrically open. A branch with an integrated fuse is in parallel with the main conductor and linked at two connecting points between the two electric voltage sources while the connecting points includes a movable section which under pre-determined conditions moves from contact with the main conductor into an alternate position in contact with the supplemental conductor, resulting in an open circuit across the main conductor and a closed circuit across the supplemental conductor.

Abstract: A direct current interrupting switch assembly comprising a primary conductor and a secondary conductor integrated with a direct voltage source and a load. The primary conductor of the switch assembly has two branches, the first branch including a fuse with a melting member and the second branch including a pyroswitch with an interrupting member. In a first position, the second branch of the primary conductor is uninterrupted, and the interrupting member is a sufficient distance apart from the secondary conductor. When the interrupting member is moved to a second position, the current in second branch of the primary conductor is interrupted and the interrupting member contacts the secondary conductor of the switch assembly.

Abstract: The disclosure refers to a switch which is suitable to protect an electric circuit against overloading. The switch generally consists of a triggering assembly as well as of an interrupting assembly, wherein said triggering assembly comprises and induction unit, a thermic interrupter and an actuating needle. The induction unit comprises a coil with a yoke intended to displace the actuating needle towards the triggering assembly, when the short circuit occurs. Said thermic interrupter comprises a bimetallic membrane, which is mechanically interconnected with the actuating needle and is in the case of excess current and generating of heat displaced towards the interrupting assembly. In order to provide such switch, which could moreover enable protection against transient voltage, e.g. due to thunder bolt, such switch is furnished with a varistor, which is located within the triggering assembly in a heat-conductive relationship with said thermic interrupter.

Abstract: The purpose of the invention is to create such a varistor fuse element, which should within a single housing include both a varistor (1) as well as an electric fuse (2), wherein said varistor part i.e. a varistor (1) is intended to protect each electric installation against overvoltage impulses and consequently against current strokes, while the fuse (2) is capable to transmit the current stroke due to increased voltage and to interrupt each permanently increased electric current, which might occur due to defects on the varistor (1). Moreover, such varistor fuse should not exceed dimensions of already known and widely used protective means, in particular melting fuses. In accordance with the invention, the fuse (2) with its round tubular casing (20) and the varistor, which is also embedded within a round tubular casing (10), are serial interconnected and arranged coaxially within each other.
