UEDASEISAKUSHO压力开关PU72W-12-RC2D-KB-M产品用于液压泵卸荷时，压力继电器不是控制液压泵停止转动，而是控制二位二通电磁阀，将液压泵5输出的压力油流回油箱，使其卸荷。当动作不灵敏，不好调：压力范围没有选对。因为弹簧不是线性的，所以压力继电器一般是分了压力等X的。X好选择合适的压力等X。
UEDASEISAKUSHO压力开关PU72W-12-RC2D-KB-M产品用于液压泵的启闭时，有两个液压泵，高压小流量泵，低压大流量泵。当活塞快速下降时，两泵同时输出压力油。当液压缸活塞杆抵住工件开始加压时，压力继电器在压力油作用下发出动作，触动微动开关，将常闭触点断开，使液压泵停转。在加工过程中减慢液压缸的速度，同时减少动力消耗。
