    • A mode selector switch for a power tool that can have a source of a magnetic field and use a magnetoresistive component to produce an output signal that changes when the strength of the magnetic field changes. The power tool can have a microprocessor that changes an operational mode of the power tool based on a change of the output signal from the magnetoresistive component. The magnetoresistive component can be a Hall effect sensor and the power tool can be a nailer. The power tool can have a switching means which changes an operational mode based upon a change in the strength of the magnetic field upon a magnetoresistive component. A method of controlling a power tool, having a step of changing an operational mode of a power tool based upon identifying a change in output from a magnetoresistor.
    • 一种用于电动工具的模式选择器开关,其可以具有磁场源并且使用磁阻部件来产生当磁场强度变化时变化的输出信号。 电动工具可以具有基于来自磁阻部件的输出信号的改变来改变电动工具的操作模式的微处理器。 磁阻元件可以是霍尔效应传感器,电动工具可以是钉枪。 电动工具可以具有基于磁阻部件上的磁场强度的变化来改变操作模式的开关装置。 一种控制电动工具的方法,具有基于识别来自磁电阻器的输出变化而改变电动工具的操作模式的步骤。
