A pressure switch is a device used to control the flow of a fluid or gas by responding to changes in pressure. It is a type of sensor that converts pressure into an electrical signal. Pressure switches are used in a wide range of applications, including industrial automation, HVAC systems, and medical devices.
Pressure switches are typically adjustable, allowing the user to set the desired pressure at which the switch will operate. This is important because different applications require different pressure settings. For example, a pressure switch used in an industrial automation system may need to be set to a higher pressure than a pressure switch used in an HVAC system.
