An elastic diaphragm pressure switch is a device that uses an elastic diaphragm (typically made of SUS316/301/304 metal materials) to sense pressure changes and perform switch operations. The working principle generally includes the following steps:

1. Pressure Change Sensing: The pressure switch has a chamber, one side of which is connected to the external pressure. When the external pressure changes, the pressure inside the chamber changes accordingly.

2. Elastic Diaphragm Deformation: The diaphragm is installed on one side of the chamber, with the other side connected to a fixed point. When the pressure inside the chamber changes, the diaphragm undergoes elastic deformation due to the pressure difference.

3. Switch Operation: The deformation of the diaphragm pushes or pulls the electrical contacts connected to it, thereby closing or opening the circuit. This switching operation can be used to control the start and stop of electrical equipment, trigger alarm systems, and so on.

This type of switch is typically used in applications requiring automatic control based on pressure changes, such as air conditioning systems, boilers, water pumps, automotive brake systems, and more. In these applications, the pressure switch monitors the pressure changes in the system, automatically controlling the operation of the equipment to ensure safe and efficient
