Auto Reset Pressure Switch

Egret BLPS-YKH & BLPS-YKL auto reset pressure switch is very popular among HVAC&R industries. We not only have high pressure switch, open on pressure drop, closes on pressure rise. But also have low pressure switch, open on pressure rise, closes on pressure drop. On the other hand, pressure switch can divide to SPST(Single pole single throw), and SPDT(Single pole double throw). Moreover, it is a type of cartridge mini pressure switches or controls. In terms of pressure connection ports, it has BSP 1/4, BSP 1/8, 3/8, 1/2, G 1/8, G 1/4, NPT 1/8, SAE 1/4 female flare with deflator 7/16-20UNF. Last but not least, The available pressure setting values can be from 0.02-4.6 mpa.

Features of Auto Reset Pressure Switch

Features of Auto Reset Pressure Switch

Egret BLPS-YKH and BLPS-YKL series pressure switches are normally open & normally closed pressure switches, SPST or SPDT, quick mounting, snap-action, On/Off pressure switches, available in a wide variety of factory-setting, non-adjustable pressure setting values. Moreover, it is a basic snap disc design pressure switch mainly used in machine control applications. Plus, it is widely used in air conditioning and refrigeration systems, heat pump, water purifiers, etc. Important to realize, the pressure data can be set customized from 3-667 psi. And it has many types of pressure mounting ports, such as male thread, female thread, copper tube, etc. In terms of electrical connection, it can be flying leads, spade terminal, etc.

Process of Auto Reset Pressure Switch Production

Process of Auto Reset Pressure Switch Production

First, we use turning lathe and CNC milling machine, to cutting and machining different size of male and female thread, there are BSP 1/4 inch, NPT 1/8 inch etc. On the other hand, we can also use different size of straight or bending copper tube instead of thread connections.


Second, punching the metal pressure sensing diaphragms.


Third, silver soldering and laser welding, and then assembling the connection port to the disc-shaped metal diaphragm and valve core depressor.


Forth, encapsulate the whole parts with black plastic shell housing.


Fifth, factory calibrating the different customized pressure setting. Finally, wiring, acid pickling, epoxy, and inspection.
