Pressure switches used to control the operation of a filtering
system or pump. The high pressure switch is set to turn off at
40psi, and on at 20psi. Used in conjunction with a pressure tank
in a reverse osmosis system. The low pressure switch is used to
prevent the pressure boost pump from operating when the source
pressure is insufficient. The low pressure switch is set to turn
off when pressure is below 5psi, and on when pressure exceeds 5psi.
