    • A power tool includes a variable speed motor coupled to a drive member. A power circuit electrically connects the variable speed motor to a power source. A variable speed signal generator generates a variable speed control signal indicating an operating speed for the motor. The operating speed is dependent upon a value of a variable speed selection signal generated by a slide switch. The slide switch includes a linear slide potentiometer for generating the variable speed selection signal. An actuator slides along the potentiometer to control the value of the selection signal. The slide switch includes an ON/OFF contact and a lever arm that is movable into and out of contact with the ON/OFF contact. The actuator is configured to prevent the lever arm from contacting the ON/OFF contact when the actuator is in an OFF position in relation to the slide potentiometer thereby opening the power circuit.
    • 电动工具包括耦合到驱动构件的变速电动机。 电源电路将变速电动机电连接到电源。 可变速度信号发生器产生指示电动机的运行速度的变速控制信号。 操作速度取决于滑动开关产生的可变速度选择信号的值。 滑动开关包括用于产生可变速度选择信号的线性滑动电位计。 执行器沿电位器滑动以控制选择信号的值。 滑动开关包括ON / OFF触点和可与ON / OFF触点移动接触的杠杆臂。 致动器构造成当致动器相对于滑动电位器处于断开位置时,防止杠杆臂接触ON / OFF触点,从而打开电源电路。
