Introduction to Pneumatic Pressure Switch
After the motor runs, the press ure is produced and directly gets into the switch, under the action of sensing film, the thrust is developed, the pressure spring with it makes the driving plat move up to drive the spring board, and actuate the jumper spring to fast separate the moving contact from the fixed contact with the help of elastic force, so as to cut off the power, the motor will stop running immediately.
