电源开关搬弄是非的人®

磁

Tattletale指示器和磁性开关是神经中枢，将Swichgage®接触操作转化为决策，并操作报警或关机设备。这些开关是用于报警或关机设备的电气负载装置。不完整的指示器指示哪个监控功能失败导致报警或关闭磁开关没有。磁开关的工作原理基本上相当于闭锁继电器。磁性开关和Tattletale指示器可用于发动机或电动机。各种电路，时间延迟和接触配置可匹配电源和操作模式所需的报警，报警前关机或关机。对于分配器点火发动机，磁开关打开分配器线圈电路导致停机。对于磁或CD点火，磁开关接地点火输出。一些型号还可以跳闸燃料阀，而不是或除了接地点火。柴油发动机是通过关闭燃料或空气供应来关闭的。 Magnetic switches and Tattletale annunciators can make or break circuits for these engines. Features Magnetic switches and Tattletale annunciators described in this bulletin are electrically tripped relay type devices. Models are available to operate from battery power, 120 VAC, conventional magnetos and capacitor discharge type ignitions. Energized to run models allow Closed Loop circuitry. Others draw momentary power to trip. Configurations are available for contact make or contact break to cause shutdown. Some models have both make and break contacts.
