摘要： The present invention relates to an arc-quenching device for circuit breakers having double-break contacts for use in low-voltage distribution systems. Provided around a prechamber (41) is a magnetic shield (91) for the purpose of intensifying the magnetic blowing action on an arc formed between the arc guide rails (51, 61) of the prechamber. In addition, a blowing loop (81) is inserted in the arc-quenching circuit and extends in sections parallel to an arc guide rail (61). Prechamber insulation having a bulge constricting the arc area likewise serves the purpose of optimizing the arc run.

摘要： An electric switch for an electric tool with an electric motor. The switch has first electrical terminals for electrical connection to a voltage supply and second electrical terminals for electrical connection to the electric motor. The switch has an actuating mechanism which can be adjusted between an initial position and a final position, wherein the electric motor is switched off when the actuating mechanism is located in the initial position and is switched on when the actuating mechanism is not located in the initial position. The switch also has a braking circuit for braking the electric motor, the braking circuit operating when the actuating mechanism is reset to the initial position. The switch also has a reversal circuit for switching over the direction of rotation of the electric motor. The braking circuit is arranged between the second electrical terminals and the reversal circuit.
