    • PROBLEM TO BE SOLVED: To provide a low-cost push-button switch which has a high allowable current capacity and is free of restrictions on the mounting by using dimensions corresponding to two units of a standardized wiring apparatus. SOLUTION: A push-button switch is equipped with an operating part on a push-on system, a suction cup 23b moving interlockingly with the setting operation of the operating part, a card 26 for opening and closing a switch mechanism in cooperation with the suction cup 23b, a suction member 24 to make suction attachment and holding of the suction cup 23b which has moved, a return spring 27 to energize the suction cup 23b in the direction in which the suction cup 23b separates from the suction member 24, a terminal whereto the switch mechanism is connected electrically and also external leads are connected, a handle return spring to make disengagement of the operating part which has been set, and an apparatus body in which at least the suction cup 23b, suction member 24, card, and return spring 27 are accommodated, whereby at disengagement of the operation part, a time lag is provided until the suction cup 23b separates from the suction member 24, by a balance between the suction force of the cup 23b to the member 24 and the spring force of the return spring 27.

    • The invention relates to a switch (4) for electric tools with electrical braking systems, comprising an electric motor with at least one field winding (3) and one armature (2). The switch (4) has switching contacts (S1,S2) that switch between an engine mode and a braking mode of the electric motor (1). In engine mode, the field winding (3), the two switching contacts (S1,S2) and the armature (2) form an electric motor circuit that is series connected to the supply voltage (5,5',5''). In braking mode, the field winding (3), the two switching contacts (S1,S2) and the armature (2) form a closed braking circuit. At least one means of retardation can interact with the two switching contacts (S1,S2) so that the switching movement of said contacts (S1,S2) is retarded when switching from a motor mode to a braking mode and/or from a braking mode to a motor mode. The means of retardation and/or the interaction for the switching contacts (S1,S2) is designed in such a way that the delay times of the switching movement for both contacts can vary with respect to each contact (S1,S2).
    • 用于具有电制动系统的电动工具的开关（4）技术领域本发明涉及一种用于具有电制动系统的电动工具的开关（4），其包括具有至少一个励磁绕组（3）和一个电枢 开关（4）具有在电动机（1）的发动机模式和制动模式之间切换的开关触点（S1，S2）。 在发动机模式中，励磁绕组（3），两个开关触点（S1，S2）和电枢（2）形成串联连接到电源电压（5,5'，5“）的电动机电路。 在制动模式下，励磁绕组（3），两个开关触点（S1，S2）和电枢（2）形成一个闭合的制动电路。 至少一个减速装置可以与两个开关触点（S1，S2）相互作用，从而当从电动机模式切换到制动模式和/或从制动模式切换时，所述触点（S1，S2）的切换运动被延迟 到电机模式。 用于开关触点（S1，S2）的延迟和/或相互作用的装置以这样的方式设计，即两个触点的开关动作的延迟时间可以相对于每个触点（S1，S2）变化。
