车辆内部的每个功能都由开关以某种方式控制。有些开关需要高电流容量,而另一些则需要低压。低压开关通常控制继电器的电位位置,该电源将电流引导到正在操作的功能上。
什么是摇杆开关?
摇杆开关是配备弹簧按钮的电动开关。当按下一个位置时,将完成电路。如果释放了按钮,则弹簧加载的操作将按钮按下其静止位置,并且电路打开。
一些摇杆开关在同一按钮上运行多个电路。一个很好的例子是电动门锁开关。按下锁定按钮时,请命令锁定电源锁定器。释放按钮后,开关弹簧回到静止位置,尽管它保持在锁定位置,但不再将电源发送到锁定执行器以锁定门。摇杆开关的另一端是解锁按钮。当按下并释放它时,锁定器的锁定器位置相同。
Some rocker switches activate a timer and when the button is released, the function continues to operate until the timer turns off, such as a rear window defogger grid button.
它们如何在汽车中使用?
如前所述,在某些型号中,摇杆开关用作电源门锁开关。其他用途包括:
- Heated seat switches
- 后窗Defogger网格
- Power window controls
Rocker switches are popular in many kinds of systems because of their ease of use. Because the function usually turns off when the button is released or when a timer automatically turns off, they don’t require the same attention as other switches, such as a toggle switch.
