热销美国UE真空开关J400系列全现货供应

美国UE真空开关为纯机械形变导致微动开关动作。当压力增加时，真空开关作用在不同的传感压力元器件（膜片、波纹管、活塞）产生形变，将向上移动，通过栏杆弹簧等机械结构，zui终启动zui上端的微动开关，使电信号输出。机械压力开关设定方式从功能原理上均为连续位移型，设定点可单点设定并zui多可达到3个不同的设定点。

美国UE真空开关是控制管路或某封闭空间的真空度的开关，为纯机械形变导致微动开关动作。

美国UE真空开关是框架式断路器的通俗称呼，实际上就是断路器，主要作用是切断大电流的电器元件。

美国UE真空开关有负压及正负压兼顾的不同量程段的多种选择。在测负压的同时，UE真空开关可以耐受一定强度的正压，在电力行业有极广泛的应用。
