TYPE 809

 

Pressure switch

Normally closed contact (Type 809)

 

A Kant pressure switch Type 809 and 810 has an integrated N.C. / N.O. contact. When pressure is applied, a diaphragm is deformed or a piston is displaced via a lifting movement. The deformation or movement depends on an adjustable spring preload. When the switching point is reached, the diaphragm or piston has undergone a defined movement which actuates the switch and opens or closes the electrical circuit. Specific pressure values can be monitored via the switching signal.
