Product Description


High Precision Automatic Reset Micro Pressure Switch 7-10 Psi EPDM Diaphragm


Product brief: Yuanben PS-0507 manual reset high pressure switch
The pressure switch is mainly used in the refrigeration cycle system, as a control device of the system over high pressure or low pressure protection, or used in the cooling system start and stop control device controlled by the system pressure in the refrigeration unit. According to its working principle, it can also be applied to other industrial control fields, such as steam electric iron, reservoir and other industries using pressure control.

Principle
When the pressure of the controlled medium rises to a certain set value, the butterfly shaped metal diaphragm will cause instability jump, and the switch contact will be connected (or disconnected) by pushing the ejector pin. When the pressure of the controlled medium drops to another set value, the butterfly shaped metal diaphragm will suddenly jump back to the original state, which makes the switch contact open (or connected), thus realizing the switch function.

The difference between the manual type and the automatic type: when the pressure of the controlled medium decreases, the switch can not reset automatically, and the circuit always remains in the state after conversion. Only when the reset button is pressed by hand, can the circuit return to its original state.
