The type of pressure switch shown in the question is a Bourdon tube pressure switch. Bourdon tube pressure switches are commonly used in various applications to monitor and control pressure levels. They utilize a curved tube, known as a Bourdon tube, that expands or contracts in response to changes in pressure. This movement is then converted into mechanical motion that actuates the switch, triggering the desired response or signal.The pressure switch shown in the question is called a Bourdon tube pressure switch. It uses a curved tube that changes shape when pressure changes. This movement is used to activate the switch and control pressure levels.
