J-300 Flow Switch with Box End Connector

This is the flow switch for Jacuzzi's J-300 series spas that use box end connectors (which go into a small plastic harness connector). The switch is pre-installed in a "T" fitting with an arrow indicating the direction of flow. If your spa has an LCD display, this is the most likey replacement. It was officially used on 2002-2005 J-350, J-355, J-360, J-365,  J-370, J-375, J-380 and J-385 models.
