Pressure Switches 2817

The Conflow Code 2817 - FLP Pressure Switch is used to make, or break, an electrical circuit with the presence, or absence of any pre selected pressure value within its operating range.

The principle of the design is a simple spring loaded piston which converts the incoming fluid pressure to a lateral movement.

The diameter of the piston and the strength of the spring are selected to give the required piston movement for the desired pressure setting. Thus at a pre-determined hydraulic pressure the piston moves and contacts a microswitch, which is either 'normally open' or 'normally closed'.

The compression of the spring can be adjusted to fine tune the pressure setting within its operating range

Typical Applications

  • To switch the rear lights on a tracked vehicle when the hydraulic circuit for reversing is selected. The pressure of this circuit being used to trip the switch and apply the rear lights for a reverse movement warning situation


  • 1/2" BSP water connections
  • Maximum working pressure up to 210 bar
  • Switches electrical circuit when minimum (or maximum) pressure conditions is reached
  • FLP Approved - Cert # 03ATEX1537
