The Ashcroft pressure switch is a device that is combined with an

electrical switch. When the pre set fluid pressure is reached, the

switch contact acts. Mainly used for outputting alarm or control

signals on industrial equipment such as power plants,

petrochemical, and metallurgical industries, it has important

applications in the industrial field and can prevent damage to

important devices in production engineering, avoiding the

occurrence of major production accidents.
