Manual Reset Pressure Switch
Egret BLPS-YKM series of manual reset pressure controllers are suitable for overpressure protection of all types of air conditioning and refrigeration systems. When the system pressure is above the rated security pressure, the pressure induction disk within the sensor moves instantaneously, the security disk through a guide rod is driven to the lock location, while the security disk pushes the switch touch point to disconnect through the connected guide rod; when the pressure drops to the rated security pressure below, the induction disks automatically reset, while as the security disk has been at the lock location and cannot be automatically reset, the switch touch point cannot be connected, and the system can return to the normal working condition only by pressing the external button and forcing to push the security disk lock to the switch touch point into the connected state.
