There are many factors that affect the quality of pressure switches, such as diaphragms, micro switches, welding, etc. Every detail will affect the accuracy and life of the switch.We strictly control the quality of every accessory and every production process in the production process,All switches have undergone 3 pressure tests and 2 water leak tests before leaving the factory to ensure that each product can meet your requirements.All switch labels have the date printed, and the normal warranty is 1 year or 100,000 times, whichever comes first。At the request of customers, we have developed pressure switches with a long life span of 500,000 to 1 million times. We will continue to research and develop products that meet market needs.

The on and off of the pressure switch is determined by the system pressure. The system pressure will enter through the joint hole at the bottom of the switch. Air pressure or hydraulic pressure will generate a pressure on the diaphragm. The diaphragm pushes the internal high pressure sheet and diaphragm seat, and the diaphragm seat pushes the low pressure elastic sheet.When the silver point of the low-pressure elastic piece is in contact with the silver point of the high-pressure elastic piece, a low pressure is generated. The air pressure continues to increase as the system pressure increases. When the high pressure reaches a certain pressure, the high pressure diaphragm deforms and pushes the ejector rod. The ejector pin pushes the high-pressure elastic sheet to separate the high-pressure silver point from the low-pressure silver point, thus generating a high-voltage break value.

It is widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, etc., such as refrigeration systems, lubrication pump systems, air compressor etc.
