What are the applications for an AUTO-OFF Pressure Switch?

 AUTO-OFF” pressure switch (maintained manual cut-out switches) are equipped with a lever, this lever can be manually set in two positions:

AUTO – Switch operates in automatic mode controlling the pump exactly like a standard pressure switch contacts opening on rising pressure (pump stops) and contacts closing on falling pressure (pump starts)

and

OFF – The contacts are mechanically held in the open position (pump off) by a lever arm that holds the inner switch plate securely on the open position until the lever arm if manually set to the AUTO position.

This allows the home owner to shut off the pump for short or extended periods of time ideal for taking safety measures during vacations or winterizing cottages.
