FLOW ACTUATED SWITCHES

Advantages of Flow Switches:

  • Mounts further downstream in pumping system than traditional vacuum switches, therby minimizing potential leak points that can cause vacuum switches to close.
  • Vacuum switches use rubber diaphragms that often rupture and cause vacuum leaks to the pump
  • Flow switches operate at a variety of pressures
  • Flow switches eliminate the need to restrict water flow to the pump, thereby prolonging pump life
  • the reed switch is encased in a protective glass capsule with a sealed nitrogen atmosphere that eliminates exposure to corrosive cleaning chemicals

ST-5 3/8F FLOW SWITCH
The ST-5 is a "normally open" flow switch, designed to be mounted in a high pressure water line. Inside the housing is a floating magnet which is aligned parallel with a reed switch. When the water flow is initiated, usually by pulling the spray gun trigger, the water flow forces the magnet to move forward. Once in the correct position, the magnet pulls the thin reeds together, closing the circuit and allowing electrical continuity. When water flow ceases, usually when the trigger is released, gravity returns the magnet to its original position. the reeds then pull apart and open the circuit, stopping electrical continuity.

Advantages of Flow Switches:
  • Mounts further downstream in pumping system than traditional vacuum switches, therby minimizing potential leak points that can cause vacuum switches to close.
  • Vacuum switches use rubber diaphragms that often rupture and cause vacuum leaks to the pump
  • Flow switches operate at a variety of pressures
  • Flow switches eliminate the need to restrict water flow to the pump, thereby prolonging pump life
  • the reed switch is encased in a protective glass capsule with a sealed nitrogen atmosphere that eliminates exposure to corrosive cleaning chemicals
Specifications:
  • Mounting Position: Vertical only
  • Magnet Configuration: Free floting
  • Pressure, Minimum: 75 PSI
  • Pressure, Maximum: 3600 PSI
  • Flow Rate, Minimum: 1.0 GPM
  • Flow Rate, Maximum: 8.0 GPM
  • Inlet: 3/8" FPT
  • Outlet: 3/8" FPT
  • Cord/Lead Length: 47 inches
  • Weight: 16 oz
Wiring Instructions:
  • Lead #1 to Line/Power
  • Lead #2 to Load
  • Yellow with green tracer to Ground
Reed Switch Adjustment: depending on the system flow, it is normal for the magnet position to vary. This variance may require adjustment of the reed switch upon initial installation, especially at lower flow rates. If the switch fails to close upon initial flow, simply loosen the adjustment screw and position switch so it properly opens/closes according to flow conditions.

The ST-6 flow switch is a "normally open" flow switch, designed to be mounted in a high pressure water line. Inside the housing is a floating magnet which is aligned parallel with a reed switch. When the water flow is initiated, usually when the spray gun trigger is pulled, the water flow forces the magnetto move forward. Once in the correct position, the magnet pulls the thin reeds together, closing the circuit and allowing electrical continuity. When water flow ceases, usually when the trigger is released, a light spring returns the magnet to its original position. The reeds then pull apart and open the circuit, stopping electrical continuity.

REED SWITCH
The basic Single Pole, Single Throw, Normally Open (SPST-NO) reed switch has two ferromagnetic reeds which are hermetically sealed into a glass capsule. This capsule contains a vacuum. The flattened reeds overlap and are separated by a small gap in the contact area. The contact surfaces are plated with the precious metal Rhodium.

In the presence of a magnetic field, the reeds become flux carriers and attractive polarities are set up between the contacts. Closure occurs when the magnetic force exceeds the reed's spring rate. Contacts open when the magnetic force is reduced to less than the reed's restoring force.
