WSA-BAL Pressure switch is one of the products introduced from LINCOIN(GmbH),applied to monitor and determine the working pressure predefined in the end of concentrical lubrication system,and to sent a signal to central pumpto control is operation.

This switch is composed by piston,spring and limit switch.The spring press force can adjust same range on locale.The system pressure overcomes the spring pressure predetermined by the piston,to push the limit switch,and make to turn on the electro points,and sent a signal to the controller.

Appearance and dimensions

According the pressure scale needed of this switch,the diameter of piston and of piston and of spring must matched prearrange.The data follews.
