pls series plastic level switches

PLS Series Plastic Level Switches

The Levelpro PLS Series compact level switches combine low cost and reliability with fast, simple installation. The all plastic level switches contain an hermetically sealed reed switch that is actuated by magnets that are permanently bonded inside the float. They can be easily adapted to open or close a circuit based on the rising or falling of the liquid level. The switch action can be reversed by removing the float, rotating it end-for-end and replacing it on the stem. Vertical models mount internally, oriented within 45° of vertical, or select optional fittings for external mounting. Switch ratings are suitable for many solidstate control systems and small monitors or alarms. Simple relay interfaces can be used for higher current applications such as pumps and on-off valve actuators.
