Model / series: F6/F7 Vertical
Series F6 and F7 vertical level switches mount through the top or side of a tank at the high or low level point. A magnet in the float operates a hermetically sealed reed switch, and the contact can be made normally open or normally closed, so one model covers rising or falling level alarms and pump control.
