  双电路技术是指在一个轻触开关(单刀双掷,SPDT)内部产生两个独立输出信号的功能。请参见下面的SPDT电路。KSC DCT轻触开关有一个共用引脚、一个常关(NC)引脚和一个常开(NO)引脚。如果用户选择同时使用常关和常开电路,则可提供转换信号,并允许用户使用这两种电路来定义信号的逻辑,并根据定义的逻辑进行操作。

  以汽车门把手为例,在做出任何决定之前,都要同时使用NC和NO电路。逻辑处于静止状态,NC触点关闭,NO触点打开。当用户按下按钮时,在NC触点打开和NO触点关闭之前不会发生任何事情。见下表,这样客户只需正确执行一个逻辑,其他三个都是故障。

  主要优势:

  · 增强功能:KSC DCT开关可实现更复杂的控制方案,从而增强用户体验和设备功能;

  · 多功能性:单个输入可连接到两个输出中的一个,从而可以通过单个开关控制多个电路或功能;

  · 紧凑型设计:KSC DCT轻触开关将多种功能集成到一个开关中,占用面积仅为6x6毫米,节省空间,对紧凑型设备至关重要;

  · 可靠性:为用户提供清晰的触觉反馈,确保可靠和精确操作,对于精确控制至关重要的应用尤为重要;

  · 简化电路设计:使用SPDT开关可以减少电路中所需的开关和接线数量,从而简化整体设计,并有可能降低电路的成本和复杂性。

  应用领域:

  · 汽车应用

  · 医疗器械

  · 消费电子产品

  · 工业设备
