Dual in-line package or DIP switches are manual electronic switches that, along with other switches in one package, form one unit. They usually mount on printed circuit boards through pins. Some common types of DIP switches include rotary, slider and rocker switches. Through them, end users configure circuit boards or controllers for the application at hand. In the case of rocker DIP switches, the setting is either an on or off position. In the case of rotary DIP switches, a dial can set to any number in an array of positions.
Using DIP switches gives designers various control options over a stepper motor. Some DIP switches let the designer change the step size, current, speed and more. Advantages of DIP switches include no need to use software programs to configure a stepper drive to operate a motor. Simply set the switches in the desired position and the motor will run in that manner. That in turn eliminates the need to connect the drive to a computer.
另一个优点是，没有必要向系统通电以了解其状态。DIP-Switch切换或拨号的位置表示驱动器设置为可行。DIP开关也廉价且易于使用和结合到设计中。
尽管有这些优势，DIP开关确实有缺点。如果空间是一个问题，则DIP开关可以庞大，尤其是在设计中需要许多设置选项的设计。远程配置是不可能的，因为交换机需要手动（物理）调整。
One alternative to DIP switches is software control, which requires a computer in conjunction with a drive. This means the end user must either write a program to configure the drive, or use a program provided by the manufacturer. This is why as much as industries move toward configuring via software, DIP switches — with their simplicity and ruggedness in a low-cost setup — remain a hardware element of configuration.
DIP开关的其他物理替代方案包括针跳线，电子巴士和焊接桥。焊接的桥梁是次优，因为它们需要焊接和卸载以进行任何变化。Pin跳线比DIP开关和半永久性便宜，但它们也很大，易于丢失。电子巴士小型且高度可配置，但需要计算机。更重要的是，电子总线也是一个潜在的混乱点，因为硬件和软件错误现在可能看起来都是相同的。
提示：对所有可用选项的利弊权衡应用程序的独特要求。还与Stepper-Drive制造商联系起来。
