Abstract: The invention relates to a switch for electrical hand tools, comprising: a housing, switch means incorporated in the housing, at least one wire opening arranged in the housing for throughfeed of a connecting wire, at least one contact incorporated in the housing for making galvanic contact between a connecting wire placed through the opening and the switch means, and at least one sealing element fitting into the at least one wire opening, manufactured from a flexible material and provided with a throughfeed opening, wherein the sealing element has a first part in which a throughfeed opening has a diameter decreasing in the direction toward the interior of the housing. Due to this measure a very effective seal is obtained since the opening with decreasing diameter is widened slightly when the wire is inserted, whereby the seal is forced closely against the wire. This effect is improved when the opening formed in its first part is at least partly conical.

Abstract: The invention relates to a control circuit for controlling a DC voltage power supply, whereby the control circuit comprises a switching element connected in series to the motor and a bypass switch connected in parallel to the electromotor for braking the electromotor by means of bypassing, with the bypass switch being formed by a semiconductor and the control circuit comprising a control circuit for controlling the bypass switch and a detector connected to the control circuit for detecting the status of the switching element. Semiconductors are less sensitive to vibrations and dirt. They are furthermore so small that they can easily be mounted on the same carrier as the other components of the control circuit. The control circuit is preferably arranged for gradually increasing the conductivity of the bypass switch once the switching element is open. Mechanical shocks when the tool is switched off are prevented by means of the partial conductivity of the semiconductor switch.

Abstract: A drive circuit for an electric motor, comprising a switchable DC/AC frequency converter, control means for controlling said frequency converter to deliver a pulse width-modulated excitation signal to the motor, setting means for providing a setting signal for setting a desired motor operation, and comparator means for comparing the current motor operation with the setting signal for driving the control means. The simulator means are arranged for analog simulation of the electrical behaviour of the motor for the purpose of comparing the current motor operation with the setting signal. In an embodiment, a first-order low-pass filter is used for simulating the motor behaviour for the purpose of providing an essentially constant relation between the effective stator voltage and the stator frequency so as to retain a sufficiently large motor torque in the case of an increasing frequency.
