SW 108 Check Valve Switch

Contegra's SW 108 is a rugged, versatile tilt switch.  The SW 108 was designed to provide pump discharge flow sensing for pumps which use a check-valve arm.  The SW 108 fastenes directly to the arm.  When the check valve opens and the valve arm tilts upward, the switch toggles, signaling pump flow.  The SW 108 is available in two forms: 

  • The SW 108-M     The SW 108-M (Mercury) has been discontinued ... 4/2023
  • The SW 108-E      Environmentally friendly mechanical switch (moderate differential)
