电子压力开关基于压力传感器，一旦达到特定压力，即可触发电气开关操作。例如，如果机器内部的压力达到定义为临界的极限，则电子压力开关可能会中断机器的电源。

　　Electrical pressure switches are based on pressure transducers and can trigger an electrical switching operation once a certain pressure is reached. For instance, an electrical pressure switch may disrupt the power supply of a machine if the pressure inside the machine reaches a limit defined as critical.
