下面一一解释这个名词的含义：1开关。开关是指在电路正常的工作条件或过载工作条件下能接通、承载和分断电流、也能在短路等规定的非正常条件下承载电流一定时间的机械开关电器。2隔离器。具有隔离功能的电器称为隔离器，它不具备接通断开负荷电流的功能，相当于以前的隔离开关。隔离器具有以下特点：断开触头之间距离应该可见或能明显表示“闭合”和“断开”状态；隔离器应能防止意外闭合；应有防止意外断开隔离电器的锁定措施。以下电器可以作为隔离电器：隔离器、隔离开关、隔离插头；插座与插头；连接片；熔断器；具有隔离功能的开关和断路器；不需要拆除导线的特殊端子。

单P漏电开关和双P漏电开关，有人私聊我说，到底这两个哪里不一样？今天就说说它们之间的不同之处。这是单P漏电开关，大部分的家里全安装的是这样的，它有什么作用哪？它管的是短路和漏电，图上的接线端两进两出，没错，但是它只负责L（火线）的漏电，看到那个蓝色的开关了吗？只负责火线的闭合以及断开，零线在里面是直接连上的，保持长期闭合状态，跳闸也好漏电也罢，只能断开火线的，零线的漏电它是不会跳闸的。下面看看双P漏电开关。
