Three Switches for Three Very Different Applications:
Reverse Action
Cut-in (close the contacts) on rising air or water pressure. Designed to ground ignition
on gas driven pumps and compressors when desired maximum pressure is reached.
Can also act as low pressure alarm or to prevent pump operation at low pressure.
Reset lever optional.
GARD-IT
®
Wired in series with a conventional pressure switch. When failure of the water
or air supply causes system pressure to fall considerably below the cut-in point of the
regular pressure switch, the GARD-IT will disconnect the pump motor. When the
water or air supply returns, the system is placed in automatic operation by depressing
the manual reset lever until system pressure exceed the GARD-IT cut off level.
HI-GARD
®
Wired in series with any system pressure switch, this special pressure switch is
designed to cut-out (open the contacts) when a preset pressure is reached. Must be
manually reset. HI-GARD pressure switch is used when it is desirable to limit the
maximum pressure in a system.
