Function

Adjustable pressure switches are designed to control the minimum and maximum pressure of compressed air in a pneumatic system or in a circuit. Are made with a NO/NC electrical contact capable of controlling an electrical load of 0.5A with a voltage of 250V. It is advisable to mount the pressure switch vertical to the line to control, in order to avoid collecting of impurities or condensate inside the body, which could block the regular operation or change the switching pressure. Through the adjustment screw, the value of the switching pressure can be recreated after removing the contact holder.
