LS-159000 – Compact Type Bottle Level Switch

A bottle level switch is ideal for large or small tanks or where access to the inside is impractical or impossible. These units mount completely outside the tank, at the level actuation point. LS-159000 Series – Low Cost, Compact Aluminum Housing with inline NPT Ports.


When the magnetic field of permanent magnet inside the float is moved into to the proximity of the reed switch inside the stationary stem, the reed switch contacts “snap” together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch contacts move apart and the circuit is opened.
