Suttner ST-6 Flow Switch

Part Number: 1249
Equipment Type Pressure Washer
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.
Mounts further downstream in pumping system than traditional vacuum switches, thereby minimizing potential leak points that can cause vacuum leaks to the pump
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 galss capsule with a sealed nitrogen atmosphere that eliminates exposure to corrosive cleaning chemicals
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.
