压力开关是一种简单的压力控制装置，当被测压力达到额定值时，压力开关可发出警报或控制信号，如今被广泛引用于制热制冷、空调、汽车等众多工业领域，对其所应用的系统进行控制时，检测工作介质的压力。压力开关的工作原理是先设定一安全压力，当系统内的压力高于或低于安全压力时，开关内的感应片因加压流体发生形变，继而通过连接的导杆推动开关接头接通或断开；当压力降至或升至安全压力范围内时，感应片快速复位，开关随之自动复位，达到控制被测压力的目的。压力开关采用的弹性元件有单圈弹簧管、膜片、膜盒及波纹管等，而膜片式压力开关由于具有测量*、操作简便、性能稳定、使用灵活、适用范围广等优点，因此具有较为广泛的应用。现有技术中对于膜片式压力开关中的膜片一般采用焊接的方式固定在压力开关中，焊接的时候会产生较高的温度，对于不锈钢材质的膜片而言，这种固定方式往往会导致膜片变形，参照不对，成品率较低，甚至影响后续的使用，增加生产的成本。
