APG LF Series Miniature Float Switches

LF Series miniature liquid level switches have been designed for reliable operation in small tanks and containers. Their rugged design and careful engineering make them the perfect solution for OEM and large volume applications.

The stem of these miniature liquid level switches contains a hermetically sealed reed switch. The float contains a permanent magnet. As the float rises or falls with the level of the liquid, the reed switch is activated by the magnet. On most models, the operation of the switch, normally open (NO) or normally closed (NC), is easily changed by removing a retaining clip and inverting the float.

Typical applications include automatic vending machines, photocopiers, small collection tanks, miniature pumping stations, pilot plants and similar small system applications.
