Abstract: The invention relates to a method for detecting electrical currents on or near electrical conductors with at least one reed switch as a magnetically responsive switch, which is arranged near the electrical conductor such that when there is a significant current flow through the conductor, the magnetic field created triggers the switch and initiates evaluation electronics connected to the switch. For the detection of surge current variables and differentiation between long-term pulsed currents and short-term pulsed currents, a plurality of reed switches is arranged at pre-determined, different, increasing distances from the electrical switch, the evaluation electronics determining the response and the switching times of the respective reed switches. The surge current variables are determined from the association of the determined values with the respective reed switch and the pulse shape from the switching time.

Abstract: A tool for multi-component injection molding of plastic toothbrush bodies 4 for toothbrushes has two tool halves 1, 1′ which can be opened and closed. In one tool half 1 a linearly movable transfer device 6 is arranged. The hollow mold spaces 2 for injection molding the first component are formed exclusively by the two tool halves 1, 1′. For transferring the injection-molded blanks (3) in the second station, the transfer device 6 moves into the area of the injection-molded blanks 3, picks them up by vacuum suction cups 11, and transfers the injection-molded blanks 3 by linear movement into the second station.
