The Hubbell Gard-It Pressure Switch 69WC7 is specially designed to protect your water pump or air compressor motor by automatically shutting your pump off when water or air pressure falls to a level at which continued operation could damage it. Once pressure returns to normal, you simply press the manual reset button to restart your system. The switch is also designed to stop your pump whenever your water or air pressure has reached a level at which the pump is no longer necessary for proper circulation. You install the Hubbell 69WC7 along with a regular pressure switch.
