4、高压开关安装在高压管路中，一般装在储液干燥器上，串联在压缩机电磁离合器电路或冷凝器风扇电路中。当系统压力过高时，高压开关动作，切断离合器电路或接通冷却风扇高速挡电路，防止压力继续升高，避免造成系统的损坏。
汽车空调压力开关坏了的现象是：触点接触不良或压力开关动作失常而造成压缩机不工作或不起正常的压力保护作用。
汽车空调压力开关的检修方法：
1、检测压力开关的通断性
用万用表欧姆挡测量压力开关的4M1与4M2端子之间的电阻，电阻应为0。如果电阻不为0，说明压力开关的常闭触点接触不良，需更换压力开关；
如果电阻为0，则进行压力开关

高低压开关的设定值是根据系统采用的制冷剂（12、22、502、134a等）的压焓曲线和系统设计的冷凝压力和蒸发压力来决定的，同一制冷剂又因冷却方式（风冷、水冷）而冷凝压力不同。
低压开关室装在压缩机的回气管上的，当压力过低时开关保护动作，而高压开关室装在排气管上的，当高压过高时开关动作。以便保护压机和系统的安全。
